This AWS blog postseems to weigh the options well.Automated backups are limited to a single AWS Region while manual snapshots and Read Replicas are supported across multiple Regions.Having cross region Read replica would give you the best RPO and RTO as you canpromote replicato be an independent instance which should improve your RPO / RTOAlternatively, if you choose to useAmazon Aurora Backtrackit seems to offer a similar option to having a read replica but I do not have a personal experience with this feature so can't say how effective it is in improving RTO and RPO.

We are running AWS RDS PostgreSQL, with daily automatic snapshots, encrypted by AWS managed KMS key. My objective is to minimize risks and data loss, in case when main AWS account (running RDS) got compromised or RDS deleted/damaged in some way.What we've implemented so far: RDS snapshots are shared with different (backup) account, periodically copied to backup account and re-encrypted with the KMS key from the backup account, to make copies local, and independent from the main AWS account.I'm wondering if there are better ways to minimize recovery time objective and recovery point objective in case of a disaster event?

You don't want a PutItem with a ConditionExpression for this case.You need to use theUpdateItemAPI. UpdateItem is an "upsert", so if the primary key does not exist, the API will cause a new item to be inserted. This API accepts anUpdate Expressionwhich can be used to set, modify, and/or remove one or more fields from the item. Update Expressions have a few special functions available to them, and in order to prevent overwriting existing data, you should useif_not_exists(path, operand). Ifpathdoes not exist, DynamoDB will put the result ofoperandatpath. Ifpathdoes exist, it will be unchanged.The update expression for your case would look something like this:SET if_not_exists(date_created, :right_now), other_field_1 = :value_1, other_field_2 = :value_2
|
So I'm trying to put an Item into a DDB table (nodejs). If the Item has a 'date_created' attribute, I want to update all fields in that Item except for the 'date_created'.I've looked at conditional expressions and from what I understand it's pretty binary. If condition == true then proceed, if not, then don't. What I'm looking for is to do the put no matter what but don't update 'date_created' if it exists.Is this possible? Am I even approaching this with the right mindset?

I'm using AWS Quicksight for an Analytics dashboard and I have multiple databases that have the same tables. I then set a Data Source for each database. Now, I've been trying to create a Data Set for a table, let's say "products" table, which should be a UNION of all the "products" tables of all the databases.So far, I've only been able to combine data from those databases using the UI to do a JOIN. However, for the Analysis I'm trying to create, I'll be needing to do a UNION. How do you do a UNION from multiple different databases in AWS Quicksight? Thanks.

The ElasticSearch has now been implemented as ofMoto 2.2.20Other unimplemented services/features can be mocked like so:import boto3
import botocore
from unittest.mock import patch
orig = botocore.client.BaseClient._make_api_call
def mock_make_api_call(self, operation_name, kwarg):
if operation_name == 'UnsupportedOperation':
# Make whatever changes you expect to happen during this operation
return {
"expected": "response",
"for this": "operation"
}
# If we don't want to patch the API call, call the original API
return orig(self, operation_name, kwarg)
# add supported services as appropriate
@mock_s3
def test_unsupported_feature()
with patch('botocore.client.BaseClient._make_api_call', new=mock_make_api_call):
function_under_test()This allows you to completely customize the boto3 behaviour, on a per-method basis.Taken from the Moto documentation here:http://docs.getmoto.org/en/latest/docs/services/patching_other_services.html

I'm using moto to mock out aws services to write my test cases and supported use cases is fine:@mock_sts
def test_check_aws_profile(self):
session = boto3.Session(profile_name='foo')
client = session.client('sts')
client.get_caller_identity().get('Account')But there are a few services like es that isn't supported at all. How do I begin to mock this?I've tried this alternative mocking approach for testing but not sure if there's a better approachdef test_with_some_domains(self, mocker):
mocked_boto = mocker.patch('mymodule.boto3')
mocked_session = mocked_boto.Session()
mocked_client.list_domain_names.return_value = ['foo-bar-baz']
mymodule.function_call()
mymodule.py
def function_call():
session = boto3.Session(profile_name=my_profile)
client = session.client('es', some_region)
domain_names = client.list_domain_names()

How do you mock an aws service that's not mocked by moto?

Just make sure you are using the correct regions. Here is the list of the regions you can use ASK trigger with.US East (N. Virginia)
EU (Ireland)
US West (Oregon)
Asia Pacific(Tokyo)you cannot use other regions to trigger ask.Also, I think there is a limit to the size of data you can send in session attributes. It should not exceed 24kb.

I am developing a skill for Alexa using NodeJS running in AWS Lambda functions. The skill works great in my location (Europe) but my client from USA gets errors. The NodeJS uses SessionAttributes and that is what I believe it fails, since the intents that don't have sessionAttributes they are triggered in USA but the rest of intents fail.I thought it could be because my AWS Lambda function is in Europe, so I created/duplicated one in USA through my AWS account portal and configured it in alexa developer console as follows:Unfortunately keeps failing. Also, I changed the USA lambda function to default Region(1) but same fails in usa and works great for me.We tested the skill with both echo device and through the Alexa developer console Test Page.I would really appreciate some advice if someone knows a workaround or had this issue before. The NodeJS code of the lambda functions is confidential and works great so surely it is something from the regions.

You shouldn't include the port with the host name, but specify it with the-poption.So instead of-h XX.XXXXXXXX.us-east-1.rds.amazonaws.com:5432use-h XX.XXXXXXXX.us-east-1.rds.amazonaws.com -p 5432

I realize this answer is a bit late and ran into a similar issue myself. According tothisyou might have better luck being explicit about your python executable and using the --python-installation flag. Try something likepython scripts/ebcli_installer.py --python-installation /path/to/some/python/on/your/computeror to be extra explicit/path/to/your/exact/python scripts/ebcli_installer.py --python-installation /path/to/some/python/on/your/computerThis is part of the "Advanced Use" section on theEB CLI github

I am not sure about BitBucket, but natively on AWS, you can push the logs from CodeDeploy agent to CloudWatch Logs using the CloudWatch Logs agent [1]. Once in CloudWatch Logs, you will create a Metric Filter to Alarm when some specific text appears in the log entries [2].CodeDeploy agent log file locations are:LINUX
*** /opt/codedeploy-agent/deployment-root/deployment-group-ID/deployment-ID/logs/scripts.log
*** /var/log/aws/codedeploy-agent/codedeploy-agent.log

The issue came from insufficient memory limit that was set to default 128MB.
When I increased to 256MB the connection worked as expected and it retrieved the page content.
So it turns out AWS kills the lambda when it reaches the max memory limit without any message in CloudWatch (you do get it if it gets killed by timeout though)
|
I'm trying to fetch the content of a webpage from AWS Lambda but it fails silently, CloudWatch logs just contain the following lines (timeout is set to 10secs so that's why duration is 10000ms):START RequestId: f101849f-1219-411b-8875-8944a76de937 Version: $LATESTEND RequestId: f101849f-1219-411b-8875-8944a76de937
REPORT RequestId: f101849f-1219-411b-8875-8944a76de937 Duration: 10008.39 msThe code I'm running just takes the URL and reads the content. It works fine from local environment but it doesn't when testing on AWS Lambda:public class TestHandler implements RequestHandler<Object, String>{
@Override
public String handleRequest(Object o, Context context) {
try {
Connection con = HttpConnection.connect(new URL("https://www.google.com"));
con.timeout(40000);
return con.get().getAllElements().toString();
} catch (IOException e) {
System.out.println(e.getMessage());
}
}
}Any AWS restriction that I'm not aware of when dealing with requests?

If you are creating theRestHighLevelClientyourself (or control the creation of this object), you can use the constructor that accepts aRestClientBuilder.UseRestClient.builder()method to create aRestClientBuilderwith a customSSLContext. The following is fromElasticsearch source code:RestClientBuilder builder = RestClient.builder(
new HttpHost("localhost", 9200, "https"))
.setHttpClientConfigCallback(new HttpClientConfigCallback() {
@Override
public HttpAsyncClientBuilder customizeHttpClient(
HttpAsyncClientBuilder httpClientBuilder) {
return httpClientBuilder.setSSLContext(sslContext);
}
});In your case you need to create an SSLContext that trusts all hosts:SSLContext context = SSLContext.getInstance("SSL")
context.init(null, new TrustManager[] {
new X509TrustManager {
void checkClientTrusted(X509Certificate[] chain, String authType) {}
void checkServerTrusted(X509Certificate[] chain, String authType) {}
void getAcceptedIssuers() { return null; }
}
}, null);The above is completely untested but may get you started. Feel free to update this answer with more details if it works for you.

I would check the target groups's health check since it is waiting for a replacement task to become healthier. Is your current deployment of ECS targets HEALTHY? If they are not, the ALB will be trying to bounce these containers to try and refresh them to have a health check passed. Also, does your CodeDeplot have access to deploy to ECR?

They do not. I received this answer from AWS support today:To start with, currently you need to have a user in the RDS database instance which is being used as a DMS endpoint[+]. IAM authentication to connect to RDS instances being used as DMS endpoint is currently not supported.In regards to above mentioned documentation[+], you can follow the steps to use the master user or non-master account for the PostgreSQL DB instance as the user account for the PostgreSQL source endpoint for AWS DMS.With this said, I have raised a feature request with our internal to check the feasibility to use IAM authentication to connect RDS instances being used as DMS endpoints. At the moment there is no ETA on when will this be implemented.[+]https://repost.aws/tags/TAsibBK6ZeQYihN9as4S_psg?forumID=60[+]https://aws.amazon.com/blogs/database/tag/dms/
|
My team is currently experimenting with IAM Database Authentication for our RDS mysql aurora clusters. We also use DMS to migrate data between DBs. However, it doesn't look like DMS support IAM authentication.Is there any support for DMS endpoints and IAM DB authentication? Or is this not the correct pattern.We tried setting the password as the token directly but the min password length for DMS endpoints is128so it's not an option.

This depends on the type of the AWS service. Unfortunately for "best effort" events you should consider writing custom reliability layer on the top of these events. You can find the list of services and reliability levels here:https://docs.aws.amazon.com/eventbridge/latest/userguide/eb-service-event.html
|
I read one of thedocson AWS cloudwatch events and it states that"Note that you cannot write a program that depends on the order or existence of notification events, as they might be out of sequence or missing. Events are emitted on a best effort basis."Is it true for AWS cloudwatch events in general i.e. it is a best effort service and not a guaranteed one for all services on AWS?

You need to provide a credential to aws, so to looks less explicit you can add to the boto3 client a config:from botocore.client import Config

I am new to terraform and aws. I have a requirement for provisioning elasticache redis with cluster mode disabled. I have gone through the documentation of aws_elasticache_replication_group resource and it specifiesprimary_endpoint_addressas the address of the endpoint for the primary node in the replication group, if the cluster mode is disabled.And according to theaws docs:For Redis (cluster mode disabled) clusters, use the Primary Endpoint for all write operations. Use the Reader Endpoint to evenly split incoming connections to the endpoint between all read replicas. Use the individual Node Endpoints for read operations (In the API/CLI these are referred to as Read Endpoints).My question is on how can we get the reader_endpoint_address from

There are a lot of ways to get data into redshift.
But even inside amazon there's only one way getting data out of redshift:unload to s3https://docs.aws.amazon.com/redshift/latest/dg/r_UNLOAD.htmlOn the other hand microsoft appears to provide a connector
For migrating:https://learn.microsoft.com/en-us/azure/data-factory/connector-amazon-redshift

I want to migrate from Amazon Redshift to Microsoft Azure. Is there an easy way of doing this copy?

I had the wrong function_name for the resource "aws_lambda_event_source_mapping". I was providing it themainlambda function's arn as oppose to thealiaslambda function's arn. Once i switched it to the alias's arn, I was able to successfully divide the traffic from the stream dependent on the weight!From aws doc:Simplify management of event source mappings – Instead of using Amazon Resource Names (ARNs) for Lambda function in event source mappings, you can use an alias ARN. This approach means that you don't need to update your event source mappings when you promote a new version or roll back to a previous version.https://docs.aws.amazon.com/lambda/latest/dg/aliases-intro.html

I'm trying to create a lambda alias for my lambda function using terraform. I've been able to successfully create the alias but the created alias is missing the dynamodb as the trigger.how the event source is set upresource "aws_lambda_event_source_mapping" "db_stream_trigger" {
batch_size = 10
event_source_arn = "${data.terraform_remote_state.testddb.table_stream_arn}"

)}"
}
}The lambda works with the dynamodb stream as a trigger
The Alias for the lambda is successfully created.
The Alias is using the correct version
The Alias is using the correct weight
The Alias is NOT using the dynamo-db stream as the event source

I had the same problem. The issue was because our zipped code in S3 passed the 51kb limit. My zipped code is 62kb. I deleted some files, tested it again, and it worked.

I'm trying to set up a deployment process as follows: Travis-CI.com grabs the codebase (NodeJS), builds and tests it, uploads it to S3 as a zip and then kicks off a CodeDeploy deployment (ECS). Here is my.travis.yml:language: node_js
node_js:
- '12'
before_deploy:
- zip -rq latest *
- mkdir -p upload
- mv latest.zip upload/latest.zip

It looks like key condition expression does not supportNOT begins_with(x). This might be because the result set is not contiguous (it's the items beforex, aggregated with those afterx).Some possible solutions are:make thegameScoreIda non-key attribute (or replicate it into a new non-key attribute), then you can query on theuserIdand filter on thegameScoreId(you cannot filter on key attributes), orscan the table, in which case you can apply the filter expression that you want to use (obviously you will have performance concerns with very large tables)

I am trying to run a DynamoDB query that says I want items that do not begin with a particular value. I cannot seem to find a way to do this.I have tried the following 4 ways of evaluating, and none of them work. Each one gives me an invalid operator error.MyKeyConditionExpression(s) that I have tried look like this:!begins_with(gameScoreId, :scoreScore) AND !begins_with(gameScoreId, :scoreLevel) AND userId = :userId
<>begins_with(gameScoreId, :scoreScore) AND <>begins_with(gameScoreId, :scoreLevel) AND userId = :userId
NOT begins_with(gameScoreId, :scoreScore) AND NOT begins_with(gameScoreId, :scoreLevel) AND userId = :userId
begins_with(gameScoreId, :scoreScore) = false AND begins_with(gameScoreId, :scoreLevel) = false AND userId = :userIdIf I remove the not operators, I get this error:KeyConditionExpressions must only contain one condition per keyIs there a way to do this in dynamodb?

Both Amazon SNS and Amazon Pinpoint, supports sending push notification to various devices (e.g Android, iOS etc)The major difference between Amazon SNS & Amazon Pinpoint is that :with Amazon SNS you have to set up your application to manage each message's audience, content, and delivery schedule. On the other hand, with Amazon Pinpoint you do not have to code these features, most of them are already built in. With Amazon Pinpoint, you can collect data about your app usage, create highly-targeted segments and send full campaigns(either immediate or scheduled) plus many more features.
|
For the purpose of sending push notifications from the backend, if we need a Push Notification Platform, could you please suggest which of these is intended for that purpose – Amazon SNS or Pinpoint?

I have a AWS Educate Starter Account, and I want to be able to generate automatically my credentials (aws_access_key_id,aws_secret_access_key,aws_session_token) from my code.Currently, the way I do it is:1) Login with my university email and password inlabs.vocareum.com2) Click on Account Details and copy and paste the credentials into ~/.aws/credentials for AWS CLI3) In my Python code I use boto3 to interact with s3But I would like to do everything in my Python script, without logging in every time and copy the credentials, since they are temporary credentials (they expire every 1 hour).The type of account doesn't allow me to create and IAM User either.Thisis a similar question, but is 2 years old and doesn't have an answer on how to do it without logging in.Is there any way to do it?

Yes, cost does vary for different regions in S3 based on data transfer across regions. You can choose any AWS region that is geographically close to you to optimize latency, minimize costs, or address regulatory requirements. For example, if you reside in Europe, you might find it advantageous to create buckets in the EU (Ireland) or EU (Frankfurt) regions.It varies in case of cloudfront too based on regional data transfer. Here you can find pricing based on regionshttps://aws.amazon.com/cloudfront/pricing/
|
Can the cost be varied for using CloudFront and s3 bucket at each location?

Does cost varies for each edge location using cloud front or s3 bucket?

As discussed in the comments, the React project is hosted through Expo which uses AWS in the background, which explains why the error is on an object on CloudFront.Additionally, the object is accessible directly through the link, which means the issue is not related to AWS but more so the react project itself or an issue with the deployment through Expo.

I apologize for not providing that much detail but there is nothing I can do about it.

Today, I followedthe instructions givento perform Oracle RDS integration with S3 to import files from S3 bucket into a database directory.I was able to perform all the steps well and able to see the files imported from my S3 bucket in theDATA_PUMP_DIRdirectory on the RDS instance.When I run the querySELECT filename FROM table(rdsadmin.rds_file_util.listdir('DATA_PUMP_DIR')) order by mtime;I get the output listing the files I imported.Now, I am planning to get these files in a PLSQL block and the issue arises here. When I run something like this:DECLARE
BEGIN

LOOP
dbms_output.put_line('File name is ' || fn.filename);
END LOOP;

We're trying to have a lambda on AWS, that is scheduled to run every Monday at 9:45am.Our cron expression is in the form of:cron(45 9 ? * MON *)AWS docs explicitly state, that you there are six required fields for the crons (you can ignore seconds) - see documentation here:https://docs.aws.amazon.com/lambda/latest/dg/tutorial-scheduled-events-schedule-expressions.htmlHowever, deploying the lambda results in an error:An error occurred: ConsumerEventsRuleSchedule13 - Parameter ScheduleExpression is not valid.
(Service: AmazonCloudWatchEvents; Status Code: 400; Error Code: ValidationException)I've managed to fix it, by adding seconds to the expression:cron(0 45 9 ? * MON *)However, I'm still confused why the original expression was invalid?
AWS documentation (linked above) even provides a working expression for a task running every work day (Monday - Friday):cron(0 18 ? * MON-FRI *)which looks just like what we tried to use originally, minus the weekday range (since we want one specific weekday).Any clues?
|
Why does this cron expression is incorrect on AWS?

subfolders = []
for i in result['CommonPrefixes']:
subfolders.append(int(i['Prefix'].split('{}/'.format(folder),1)[1][:-1]))
subprocess.run(['aws', 's3', 'cp', 's3://my_bucket/my_path/{0}/{1}'.format(folder, max(subfolders)),
'C:\\Users\it_is_me\my_local_folder\{}.'.format(folder), '--recursive'])

You can run your code locally using theserverless-offlinepluginSupply your JDWP agent string via the environment variableJAVA_TOOL_OPTIONS. Be sure to setsuspend=y, to ensure you can connect your debugger before the function finishes executing. There are lots of ways of doing this — I suggest using theserverless-dotenvplugin.For example:cat >> .serverless/.env < EOF
JAVA_TOOL_OPTIONS=-agentlib:jdwp=transport=dt_socket,server=y,suspend=y,address=*:3888
EOF
sls offline --stage local --debug=*UsingJAVA_TOOL_OPTIONSshould work in AWS, according tothe docs... But your mileage may vary with tunneling etc.

I am working on a project using the serverless framework with code written in Java and deployed on AWS. I am able to deploy the lambda functions to AWS and I am also able to use the "serverless invoke local" command to run them locally.What I haven't figured out is how to attach to and debug this locally running function. I don't see any promising command line options, and the java invocation didn't make use of the $JAVA_OPTS environment variable to configure it there.

I think this sort of thing is better suited to being either in the build stage of your Docker container by usingRUNcommands, which is good for installing things or wrapped up into a single script and added into your docker image using theCOPYcommand in the dockerfile.

the delay is caused by multiple actions that need to be done when launching a training job, including provisioning the instances, downloading algorithm docker image, as well as downloading your dataset. SageMaker team is continuously improving the platform to reduce the latency. Meanwhile, if you are running your training job with deep learning frameworks, you can leverage the local mode feature to run your training job in your notebook instance when you are testing it. After that, you can launch the training job on a remote cluster to train your model against a large dataset.To enable local mode, you simply specify the instance type to be "local" when you launch a training job in notebook instance. More details about local model can be found here:https://github.com/aws/sagemaker-python-sdk#sagemaker-python-sdk-overview
|
When running a non-local instance on SageMaker likeml.p3.2xlarge, I can't use a localfile://URI and must uses3://This makes sense, since it is a new instance.However, when using the s3 URI for a 100GB datasettf_estimator.fit(s3://bucket/path/to/my/data)so I can use a larger non-local training instance, I have to wait around 10 minutes for the data to be downloaded from s3 to the instance.It seems to be an issue even on the instances with quoted 10gig/second or faster connection.Is there a way around this wait time which seems like it would become a severe problem with larger datasets?

Is there a way to bypass downloading training data on SageMaker?

DynamoDB needs a global secondary index. The@keytransform (or directive) can be added to yourschema.graphqlfile as a sibling to the already [email protected] Directive DocumentationRegarding the definition below:directive @key(fields: [String!]!, name: String, queryField: String) on OBJECTThe important thing is that the first element of the "fields" argument is the partition (or hash) key. Every subsequent element is a sort key. Together, the sort keys will determine the order or the returned results.(Doing so with causeamplify pushto create an entirely new GraphQL field on theQuerytype. The value ofqueryFieldwill be the new field name. Thenameargument is the global secondary index name.)

The AWS Console displays only S3 and Lambda, since at the moment only those two services are supported for logging data events. E.g.PutObjectetc.DeleteTableis a management event, and is listed in thedocumentationyou posted. If you configure your Trail to log all management events, all AWS services you use, including DynamoDB, will be logging these management events.Just create a new trail, and include all management events. Then in your Trail's event history you will find the events like below.
|
In AWS it is indicated that there is support to use Cloudtrail to track events in DynamoDB in the link here.https://docs.aws.amazon.com/amazondynamodb/latest/developerguide/logging-using-cloudtrail.htmlHowever, in the instructions, there is no option to pick DynamoDB anywhere (only S3 and Lambda options are available) so I am looking for any instructions anywhere on how to track DynamoDb events. Specifically I want to know when a table has been deleted.https://docs.aws.amazon.com/awscloudtrail/latest/userguide/cloudtrail-create-a-trail-using-the-console-first-time.htmlHas anyone had any luck?Thanks!

I just saw that I left this question unanswered. So, here's what I did to fix the issue.Shortly after posting this question, I tried theAWS CLI Windows Installeronce more and it worked. I still don't know why the initial installation didn't work, but I am able to upload to S3 via CLI without Python encoding errors.

I'm having the exact same issue asanother unanswered post, but I'm willing to give whatever code/setup needed to get the question answered properly.Like in the post I mentioned above, I am also trying to deploy files to S3 with the AWS CLI and I receive the same error:upload failed: ... An HTTP Client raised and unhandled exception: unknown encoding: idnaI have the newest version of Python and the AWS CLI. I can get the Python shell to import encodings.idna, but the AWS CLI process boots its own shell to run the commands I assume. Which may mean that I need to somehow inject the import statement into the AWS CLI process. I've tried to edit the aws.cmd programs (one in /bin and one in /scripts), but nearly every change stopped the program from working properly.I'm not sure what to post that can help determine what my issue is, so please let me know.

I agree with JohnRotenstein that, there needs more information to provide the answer. I would suggest you to take simple data points and simple table.
Here are step-by-step solution, I hope by doing that, you should be able to resolve your issue.Assume here is your table structure.Here I'm doing most of data types to prove my point.
create table sales(
salesid integer,
commission decimal(8,2),
saledate date,
description varchar(255),
created_at timestamp default sysdate,
updated_at timestamp);Just to make it simple, here is your data file resides in S3.Content in CSV(sales-example.txt)salesid,commission,saledate,description,created_at,updated_at

I've been trying to load data intoRedshiftfor the last couple of days with no success. I have provided the correctIAMrole to the cluster, I have given access toS3, I am using theCOPYcommand with either theAWScredentials or theIAMrole and so far no success. What can be the reason for this? It has come to the point that I don't have many options left.So the code is pretty basic, nothing fancy there. See below:copy test_schema.test from 's3://company.test/tmp/append.csv.gz'
iam_role 'arn:aws:iam::<rolenumber>/RedshiftCopyUnload'
delimiter ',' gzip;I didn't put any error messages because there are none. The code simply hangs and I have left it running for well over 40 minutes with no results. If I go into the Queries section in Redshift I dont see any abnormal. I am using Aginity and SQL Workbench to run the queries.I also tried to manually insert queries in Redshift and seems that works. COPY and UNLOAD do not work and even though I have created Roles with access to S3 and associated with the cluster I still get this problem.Thoughts?EDIT: Solution has been found. Basically it was a connectivity problem within our VPC. A VPC endpoint had to be created and associated with the subnet used by Redshift.

I noticed these error comming up to me in my AWS Glue Job so I found something that could be helpful from AWS:This WARN message is not so special, and does not mean job failure or any errors directly. I guess there should be other cause.
I would recommend you to enable continuous logging, and check both driver/executor logs to see if there are any suspicious behavior.
If you enable job bookmark, please try disabling it and see how it goes without bookmark.https://forums.aws.amazon.com/thread.jspa?messageID=927547I had dissabled bookmarks from the begining. What I check is that my Glue job writing data to S3 and got an exeption per Memory, so what I did is to repartition the data.MyDynamicFrame.coalesce(100).write.partitionBy("month").mode("overwrite").parquet("s3://"+bucket+"/"+path+"/out_data")so if you have some write opperations, I'll recommend to check how you are writing to S3

I am running a test job on AWS. I am reading CSV data from S3 bucket, running a GLUE ETL job on it and storing the same data on Amazon Redshift. GLUE job is just reading the data from S3 and storing in Redshift without any modification. The job runs fine and I get the desired result in Redshift but it returns an error which I am unable to understand.Here is the error log:18/11/14 09:17:31 WARN YarnClient: The GET request failed for the URL http://169.254.76.1:8088/ws/v1/cluster/apps/application_1542186720539_0001

The reason that your lambda is failing is that to uselistObjects, yourlambda functionneed to have the IAM permissions3:ListBucketwhich works against a single bucket (no object wildcard is needed)(docs).i.e. you shouldset your lambda's IAM policyto:{
"Version": "2012-10-17",
"Statement": [
{
"Sid": "AddPerm",
"Effect": "Allow",
"Action": "s3:ListBucket",
"Resource": "arn:aws:s3:::my-bucket"
}
]
}

I have an s3 bucket with a bunch of files that I want to access from my lambda (both lambda and s3 bucket created by the same account):def list_all():
s3 = boto3.client('s3')
bucket = 'my-bucket'
resp = s3.list_objects(Bucket=bucket, MaxKeys=10)
print("s3.list_objects returns", resp)This gives an error like so:{
"errorMessage": "An error occurred (AccessDenied) when calling the
ListObjects operation: Access Denied",
"errorType": "ClientError",
"stackTrace": [
[
"/var/task/lambda_function.py",
41,
"lambda_handler",
"list_all()"
], ...My bucket settings are shown like this on aws:{
"Version": "2012-10-17",
"Statement": [
{
"Sid": "AddPerm",
"Effect": "Allow",
"Principal": "*",
"Action": "s3:GetObject",
"Resource": "arn:aws:s3:::my-bucket/*"
}
]
}I had two questions:1) what do I set my Action field to be so that I can list all files in any folder from my lambda using boto3?2) what should I set my principal to be so that only my aws account (eg when I run my lambda) can access the buckets?

I think your solution may be a little too complex by utilizing the New Headers() method.Try this:fetch('api/public/libraries/sign-out-discourse', {
method: "POST",
headers: {
'Authorization': jwtToken
}
});

I want to add Cognito authorization to my API request so that the API Gateway can pass the information on to my Lambdas. I have read in other threads that I should add the id token as authorization header, so that is what I have tried so far.I have tried the following:fetch('api/public/libraries/sign-out-discourse', {
method: 'POST',
headers: new Headers([
// I get the idToken from CognitoUser.getSession => getIdToken()
['Authorization', idToken],
]),
})I get the error message{"message":"'Object]' not a valid key=value pair (missing equal-sign) in Authorization header: '[object Object]'."}I have tried the following:fetch('api/public/libraries/sign-out-discourse', {

]),
})I get the error message:{"message":"Authorization header requires 'Credential' parameter. Authorization header requires 'Signature' parameter.

You can use dynamodb streams and write a function that runs in lambda to capture changes and add documents to cloudsearch, flatenning them at that point, instead of keeping an additional dynamodb table.For example, within my lambda function I have logic that keeps the list of nested fields (within a "body" parent in this case) and I create a just flatten them with their field name, in the case of duplicate sub-field names you can append the parent name to create a new field such as "body-name" as the key.... misc. setup ...
headers = { "Content-Type": "application/json" }
indexed_fields = ['app', 'name', 'activity'] #fields to flatten
def handler(event, context): #lambda handler called at each update
document = {} #document to be uploaded to cloudsearch
document['id'] = ... #your uid, from the dynamo update record likely
document['type'] = 'add'
all_fields = {}
#flatten/pull out info you want indexed
for record in event['Records']:
body = record['dynamodb']['NewImage']['body']['M']
for key in indexed_fields:
all_fields[key] = body[key]['S']
document['fields'] = all_fields
#post update to cloudsearch endpoint
r = requests.post(url, auth=awsauth, json=document, headers=headers)

I'm trying to set up AWS' Cloudsearch with a DynamoDB table. My data structure is something like this:{
"name": "John Smith",
"phone": "0123 456 789"
"business": {
"name": "Johnny's Cool Co",
"id": "12345",
"type": "contractor",
"suburb": "Sydney"
},
"profession": {
"name": "Plumber",
"id": "20"
},
"email": "[email protected]",
"id": "354684354-4b32-53e3-8949846-211384",
}Importing this data from DynamoDB -> Cloudsearch is a breeze, however I want to be able to index on some of these nested object parameters (likebusiness.name,profession.nameetc).Cloudsearch is pulling insomeof the nested objects likesuburb, but it seems like it's impossible for it to differentiate between thenamein the root of the object and thenamewithin thebusinessandprofessionobjects.Questions:How do I make these nested parameters searchable? Can I index onbusiness.nameor something?If #1 is not possible, can I somehow send my data through a transforming function before it gets to Cloudsearch? This way I could flatten all of my objects and give the fields unique names likebusinessNameandprofessionNameEDIT:My solution at the moment is to have a separate DynamoDB table which replicates ouruserstable, but stores it in a CloudSearch-friendly format. However, I don't like this solution at all so any other ideas are totally welcome!

My guess: Your security group that was applied was "launch-wizard-2" which by default sets exlusion rules. You need to associate that EC2 instance with one of the two security groups listed in your second screen shot to allow TCP connections on port 22 from inbound ip range. OR you could modify launch-wizard-2 to incorporate the relevant rules to allow for ssh connection.
|
Another bad day. I have all the configuration for my ec2 instance.

I'm assuming you're going to put the command underUserData.Scripts entered as user data are executed as the root user, so do not use the sudo command in the script. Remember that any files you create will be owned by root; if you need non-root users to have file access, you should modify the permissions accordingly in the script. Also, because the script is not run interactively, you cannot include commands that require user feedback (such as yum update without the -y flag).Here's the fulldocumentationdiscussing topic

I have a use case to alert in case of SLA miss. My application emits metric on startTime (M1) & endTime (M2). If my job completes, I will be able to know SLA misses by doing metric math like (M2-M1) and having alerting on this.But if my job is stuck, I still want to get alerted by computing (currentTime-M1) (may be on scheduled basis). Is this possible with AWS CloudWatch? Non-AWS based approaches & solutions are also welcome!!

In your last block try making theprintline come beforeresult[dnsIpAddress] = "FAILURE"My guess is either there is more code than what is shown here or the line before the print statement causes a different exception.

While trying to implement aDNSRequest, I also needed to do some exception handling and noticed something weird. The following code is able to catch DNS requesttimeoutsdef lambda_handler(event, context):
hostname = "google.de"
dnsIpAddresses = event['dnsIpAddresses']
dnsResolver = dns.resolver.Resolver()
dnsResolver.lifetime = 1.0
result = {}
for dnsIpAddress in dnsIpAddresses:
dnsResolver.nameservers = [dnsIpAddress]
try:
myAnswers = dnsResolver.query(hostname, "A")
print(myAnswers)
result[dnsIpAddress] = "SUCCESS"
except dns.resolver.Timeout:
print("caught Timeout exception")
result[dnsIpAddress] = "FAILURE"
except dns.exception.DNSException:
print("caught DNSException exception")
result[dnsIpAddress] = "FAILURE"
except:
result[dnsIpAddress] = "FAILURE"
print("caught general exception")
return resultNow, if I removed the Timeout block, and assuming that a Timeout would occur, on a DNSException the messagecaught DNSException exceptionwill never be shown.Now, if I removed the DNSException block, and assuming that a Timeout would occur, the messagecaught general exceptionwill never be shown.But the Timeout extends the DNSException and the DNSException extends Exception. I had the expectation that at least the general expect block should work.What am I missing?

Exception handling in aws-lambda functions

Although lambda does not let you edit retried messages in any way before they get sent to DLQ, we canindirectlyadd a fewattributeslike below to the message that can explain why it failed.This only works for specific cases, mainly forasynchronous, non-stream-based invocationswhich basically means lambda’s native async retries orSNStriggers work butSQSbased retries, for instance, don’t. The other condition is that the exception returned/thrown must be an Error or an extension of the Error prototype for node lambdas.Something likeexports.handler = async (event, context, cb) => {
class CustomError extends Error {
constructor(message) {
super(message);
this.name = "Some Lambda Error";
this.message = message;
}
};
let error = new CustomError("Something went wrong")
cb(error);
// or just simply
cb(new Error("Something went wrong"));
};

I have a lambda trigger on an SQS queue which is configured with a DLQ.When my lambda failed the original message from the queue will be redirected to the DLQ.
Now I want to add more information to this original message (like why there was an error etc). I know that I can't modify the original message but I saw that a message can have additional message attributesRequestID, ErrorCode, ErrorMessage.How can I use/ setup them from my lambda function (NodeJS) ?

Have you checked out the sectionThe steps the Lambda function takesin the article that you have mentioned hereUsing static IP addresses for Application Load Balancers?You can get the IPs to whitelist from AWS S3 bucket as well as AWS CloudWatch stream. You can even automate the process of updating the Security Group inbound and outbound rules either by updating the same AWS Lambda function or by creating your own and using AWS SDK API calls like authorize_security_group_ingress() and revoke_security_group_ingress() via a Lambda function triggered on Object upload (new IP list) on S3.
|
I've implemented this solution provided by AWS:Using static IP addresses for Application Load Balancersbut I came across a problem.I need to whitelist some static IP's and since this solution requires for the targets to communicate to IP's instead of instances, the IP Preservation is not done on the NLB as mentioned here:Target Groups for Your Network Load Balancers.So, I can't really do a whitelist neither on the Security Groups nor on the NACLs.Does anyone have a solution to this problem while maintaining this architecture?

Lambda does not support this feature natively and, while you could conceivably build it with some combination of DynamoDB atomic counters and DynamoDB streams triggers, you should almost certainly useStep Functions.You're trying to coordinate the components of a distributed application composed of microservices, and that's precisely what Step Functions is designed to do.

ODataat its core is justRESTrelying on web standards and as such will be supported by web-standard compliant tech stack, so will work withAWS API GatewayandLambdas.However you have to ensure that you canpass custom headersandquery parametersto your function, which used to be a bit tricky.It used to be the case that you had to pass headers inside a request body as lambdas had only visibility to the request body:see this AWS technical documentation.However sinceSept 2017you can setuplambda with proxy integrationwhich will proxy request and response headers to and from your lambda verbatim.HTH.
|
I want to use Odata as a query builder in my api's hosted on aws lamda and exposed using AWS api gateway. On reading several aws documentation, I found that people have faced several issues with this earlier. Can someone please tell me about whether it's supported and if not what can be an alternative for the same?Thanks in advance!

On the server side you can check theX-Forwarded-Proto(original request protocol) and if it's heaving valuehttpyou can send redirect (http 302) to a url with https protocol..though with ALB (application load balancer you may specify a set of rules, maybe it's possible to do that there..)

I have configured the load balancer to route the request to two of Ec2 Instance running a NodeJs server. I need to direct the request coming from both http (port 80) and https (port 443) to http (port 80) of the EC2 instances in NodeJs. I have uploaded the ssl certificate to AWS and configured the load balancer to use ssl certificate. The problem is the request coming from http port doesn't automatically route to https. It has to be a server side script or snipped which I need to write in server.js which should be routing the http to https, i tried to do it and it run into endless redirection. So questions -Is there any guide to do this from AWS ?If not then how one can achieve this, any pointers or suggestions would be greatly appreciated.

As it turns out my test was incorrect and so I miss-understood howcreate_receipt_rulebehaves when theafterparameter is omitted.When theafterparameter is omitted the new rule is added as the first rule, not the last as I thought.So the answer to this question is there is no need to pass an explictnullvalue, just omitting theafterparameter achieves the goal.
|
Is there a way to make a boto3 client pass a parameter with an explict null value (as opposed to omitting the parameter entirely)?I'm trying to usecreate_recipt_rule on the boto3 SES clientto add a new receipt rule that I want to be the first rule.The AWS API docs (also pulled through to boto docs above) say this should be achieved by passing theAfterparameter with a null value:After (string) -- The name of an existing rule after which the new rule will be placed. If this parameter is null, the new rule will be inserted at the beginning of the rule listFrom testing I've found that this must be explictly passed asnull. Simply ommiting theAfterparameter results in the rule being added at the end of the list.I thought I'd be able to pass an explict value by having theAfterparameter present with an explitNonevalue. However this fails on boto3's parameter validation. i.e.client.create_receipt_rule(
RuleSetName='my-ruleset',
After=None,
Rule={ ... },
)Results in the following error:Parameter validation failed:
Invalid type for parameter After, value: None, type: <type 'NoneType'>, valid types: <type 'basestring'>I also tried passing the string'null'but that looks for a rule callednullto put the rule after rather than putting the rule at the start.Is there a way to pass an expitnullvalue to a parameter via the boto3 client?

You need to set the keepAliveTimeout="xxxx" in your tomcat connector settings to avoid tearing down idle connections.
|
We are seeing 504 errors in our ELB logs, however there are no corresponding errors in the application logs. Have increased the idle timeout on ELB and can see that no requests are taking more time than that.
Going through aws documentation found that we need to configure keep-alive time at ec2 instances to be equal or more than idle timeout to keep the connection open between elb and backend server.
Couldn't find any way to configure keep-alive time between elb and backend server. Any suggestion to do that would be helpfulWe are using tomcat-ebs for backend servers.

The context portion of your policy document can contain only String, Boolean or Numeric values. Arrays and Objects are illegal.The documentation states:The returned values are all stringified. Notice that you cannot set a JSON object or array as a valid value of any key in the context map.Source:https://docs.aws.amazon.com/apigateway/latest/developerguide/api-gateway-lambda-authorizer-output.html

I have an AWS API Gateway that uses a custom authorizer, and if the request is authorized, it triggers another lambda function. Since yesterday, whenever I call the API, I get an error saying{ "message": null }and a 500 Internal Server Error. In the response headers it saysx-amzn-ErrorType →AuthorizerConfigurationException. I can see in the logs that the authorizer is called and returns a valid policy, and that the other lambda function is not triggered. I have not (knowingly) changed the authorizer. Can anyone give me a hint what might be wrong here? I have readthisquestion but there the mistake was that the returned policy was wrongly formatted, while I didn't change my authorizer and it worked before.

This issue has resolved itself now, I suspect due to an update in Glue, or the associated infrastructure.The connectivity issue was occuring from within the PySpark REPL, and not on the actual Dev Endpoint instance itself...Anyway, for anyone else troubleshooting similar network connectivity issues with Glue, here is a list of possible causes:Dev Endpoint needs to be in a 'public' subnet*
DHCP options need to have the default setting
Security groups, security groups, security groups
Subnet should be associated with an S3 Endpoint

except:
conn.close()
logger.warn('no ok')
have_internet()It appears they do not...Also, within a properly configured Glue dev endpoint, there is no internet access.By properly configured, I mean within a public subnet (internet gateway), with S3 endpoint and internet gateway, and a working 'connection', and security groups.But still no internet access...I want internet access to be able to interrogate an on prem database, save to S3, and run another job to transform, and load to rds...Can I use glue for the extract?

Maybe this solution is a little overkill for your environment. But you couldset up a Cloudfront distribution. You should put your Elastic beanstalk url as origin and yourhttps://example.comunder CNAME, then you can decide if you want flexible SSL you can specify communication with the origin as HTTP only, or if you want end to end encryption you can specify HTTPS only (I think this would be the way to go in your particular case since you have configured your elastic load balancer to forward all requests from port 443 to port 80). Then under behavior you can select the option to redirect http to https and every request tohttp://example.comwill be automatically redirected by Cloudfront tohttps://example.comI hope this helps

+50It looks like you have to useServer Side Authentication FlowFor server-side apps, user pool authentication is similar to that for client-side apps, except:The server-side app calls theAdminInitiateAuthAPI (instead ofInitiateAuth). This method requires AWS admin credentials. This method returns the authentication parameters.Once it has the authentication parameters, the app calls theAdminRespondToAuthChallengeAPI (instead ofRespondToAuthChallenge), which also requires AWS admin credentials.TheAdminInitiateAuthreturns among other stuff the device key.
|
I've implemented in my backend Cognito with Signup and Login, MFA activation and inactivation, but now I want to implement the remember devices, to reduce SMS confirmation.For that, I've adjusted the InitiateAuth Function to the following code:$client->initiateAuth([
'AuthFlow' => 'USER_SRP_AUTH', // REQUIRED
'AuthParameters' => [
"USERNAME" => $email,
"PASSWORD" => $password,
"SRP_A" => $bigA,
],
'ClientId' => $this->getClientId(), // REQUIRED
]);This function runs properly, and returns the code in following image:https://i.gyazo.com/a439e48e2de85a094f56ed4cfee10f83.pngThen, I continue generating SRP Values, and call in the function respondToAuthChallenge, with the following code:$client->respondToAuthChallenge([
'ChallengeName' => 'DEVICE_SRP_AUTH',
'ChallengeResponses' => [
'USERNAME' => $username,
'SRP_A' => $bigA,
],
'ClientId' => $this->getClientId(),
]);Yet, It returns me an error saying: 'Missing required parameter DEVICE_KEY'.If I put a DEVICE_KEY key inside ChallengeResponses it starts returning me the error 'Device does not exist.'I've searched a lot and cannot find a way to generate the DEVICE_KEY. I've tried with unique ID and sending it in both initiateAuthand respondToAuthChallenge but the error is the same.Any clue how can I do it? I Believe that SRP code is not 100% yet, as still understanding the concept, yet, cannot understand the DEVICE_KEY part.Thanks

My previous answer was deleted because I gave a similar answer to another question asking about issues with outdated and insecure versions of Ruby, but I will reiterate the same advice I would give to anyone running into errors using an insecure version of Ruby like 2.4.3: update to 3+ or at least 2.7 and the corresponding compatible Bundler version.Note to Admins: if this answer is worthy of deletion, please delete this question as well and ask the user to repost with a supported Ruby version.

According to the MDNWebSockets are an advanced technology that makes it possible to open an interactive communication session between the user's browser and a server.That means that every websocket is a persistent connection to a specific server. In order to emit events to sockets that are in a different server you need an Adapter. For example if you are using Socket.io you can take a look atSocketIO Redis.On the other hand, to balance the load you can use an Application Load Balancer (ALB) which supports websockets and containerized applications in ECS.
|
I'm just starting to understand and solve this problem.Node.js's Socket.io or Go's Gorilla websocket solutions have a connection pool per instance. So within each instance I can say "send message to client xxx".However when I attempt to scale horizontally (by spawning additional instances), each instance has its own client connection pool, so trying to send a message to a specific client which is connected to another instance fails. I assume that's because the current instance doesn't have access to that instance's connection/memory pool.I understand that ECS automatically scales docker containers horizontally, if I were to spin up a WS server project on an ECS and have it scale another instance to the service, does AWS handle talk between socket server instances magically - or must I handle that?

I'm using Chalice to build a fairly straightforward API on AWS Lambda & API Gateway.I need a way to get access to the raw query string (i.efoo=bar&abc=123). When accessing theapp.current_request.query_paramsdictionary, it's already been processed, such that any empty parameters (foo=&bar=) have been stripped out.Unfortunately I'm working with a third-party API that sends a signed hash value in the query string, based off the raw query string. I can't verify it without the original, unaltered query string. Is there any way to access it other thancurrent_request.query_params?

I'm trying to use AWS Amplify to support email / password and Google authentication. Now, I want to store the details from Google into my user pool in AWS. I don't understand the flow here - there are many blog posts I read but most of them are just confusing.Here's what I tried to do:// gapi and Amplify included
googleSigninCallback(googleUser => {
const googleResponse = googleUser.getAuthResponse();
const profile = googleUser.getBasicProfile();
const name = profile.getName();
const email = profile.getEmail();
Amplify.Auth.federatedSignin('google', googleResponse, {email, name})
.then(response => { console.log(response); }) // is always null
.catch(err => console.log(err));
});In DevTools I have the following error in the request in Network Tab:{"__type":"NotAuthorizedException","message":"Unauthenticated access
is not supported for this identity pool."}Why should I enable unauthenticated access to this pool? I don't want to.Am I doing this right? Is it even possible or is it a good practice to store Google User details into the AWS User Pool? If it's not a good practice, then what is?Also, if I want to ask user for further details not provided by Google in the app and store them, how to do it if we can't store the user in User Pool?

This is a really broad question that basically reduces to "It works on Cloud9. How can I make it work somewhere else in the cloud?". I'm assuming this will eventually be marked closed for this reason, but here's my short answer.At the moment, there is no "migrate" button in Cloud9 that allows you to port over your environment into a different service. Because of this, you'll need to capture key details about your operating system, dependencies, and runtime requirements and use those to search out suitable service in AWS that meets those requirements.Because you're describing a non-production application with (I imagine) forgiving technical requirements, I would start by asking your employer which runtimes they prefer and go from there. Good luck!ShareFollowansweredJun 8, 2023 at 12:00ford-at-awsford-at-aws6966 bronze badgesAdd a comment|

Fromthis postto the forum message,Restore Snapshot doesn't allow --vpc-security-group-ids:You can grant access to IPs by adding rules to your VPC security group. First, you can call describe-clusters to determine the VPC security groups your cluster is using. If the cluster is not associated with any VPC security group, you can call modify-cluster and specify the VPC security group IDs you want to use. After you have associated a VPC security group with the Redshift cluster, you can modify the security group in the VPC console to allow access from certain IPs (seehttp://docs.aws.amazon.com/AmazonVPC/latest/UserGuide/VPC_SecurityGroups.html#SecurityGroupRules).Note that in order for the Redshift cluster to be accessible from outside of the VPC, the cluster needs to be set to be publicly-accessible.ShareFolloweditedOct 17, 2018 at 20:35Greenonline1,34888 gold badges2424 silver badges3434 bronze badgesansweredOct 17, 2018 at 17:08eatsfoodeatsfood1,05022 gold badges2525 silver badges3232 bronze badges1Please edit your answer and provide a link to the forum post–GreenonlineOct 17, 2018 at 17:37Add a comment|

I'm new to RDS and previously have been administrated non-cloud database. It's common monitor database error log and monitors the texts. But when it comes to RDS Postgres, there is no native service that monitors log file.
(I know now RDS MySQL/MariaDB has a functionality to publish to CloudWatch logs, but RDS Postgres still cannot do it)I guess basic scenario if we want to monitor RDS log files within AWS services, create Lambda function that download error log files periodically and save to S3 buckets. And parse it and if find error message, notify some chat service(like slack).But it is not realtime and gonna call a lot of API call.I'm wondering how people deal with monitoring log file.

)) Let's assume your public ip is 54.74.67.112.1A)) Export the port 3000 in the security group.1B))In the address bar of your browser use:
54.74.67.112:3000 .2)) To use the AWS DNS, as you basically are doing, these are the steps.2A)) In the security group you have to expose the port 80, not 3000.
So, In the address bar of your browser use:https://ec2-54-74-67-112.eu-west-1.compute.amazonaws.com/2B)) Inside the EC2 shell, you have to run your node application on the port 80 with a command like this:PORT=80 node myapp.js3)) The methods 1 and 2 are just for the development cases.
If you are using this for production, you should use the AWS service named ROUTE53.ShareFolloweditedOct 5, 2021 at 20:48answeredOct 5, 2021 at 20:33quine9997quine999777877 silver badges1313 bronze badgesAdd a comment|

I've created a Network Load Balancer for use with ECS Fargate. When I try to connect to the load balancer (using either the ELB domain name or it's IP addresses) it won't connect. I don't even see the connection in the flow logs. The machine I'm using to connect to the LB can reach the instances fine, but when I try to hit it through the load balancer I don't get a TCP connection. The security group on the Fargate containers allows anything from anywhere. The load balancer shows the instances health checks as "Healthy" but I still can't get to them.

Yes, it is, however, you won't be able to use it as a normal partition. Partitioning is usually used to reduce the amount of data being read for each query and therefore improving the query performance. This is why most of the time people chose partition keys like dt=2019-11-05. What is your actual goal here? You can achieve the same with bucketing. and just create as many buckets as many ranges you want to have.ShareFollowansweredNov 4, 2019 at 8:48IstvanIstvan7,9891212 gold badges6363 silver badges114114 bronze badgesAdd a comment|

Suppose there is an external table in AWS Athena containing a column 'Id' which is an integer along with numerous other columns.Is there a way for partitioning this table on 'Id' column by range?For example, create partition in the following manner:0 >= Id < 10
10 >= Id < 20
20 >= Id < 30
30 >= Id < 40and so on..This could be useful when the amount of data for one value of Id is not large enough. We could then keep the data corresponding to a range in one bucket and reduce the partitioning overhead.

Look in the Apache Hive documents for the details of each type of Serializer/Deserializer. E.g. for the OpenCSVSerde:https://hive.apache.org/javadocs/r2.1.1/api/org/apache/hadoop/hive/serde2/OpenCSVSerde.htmlBased on my rudimentary understanding of Java, I think you can set four parameters:LOGSEPARATORCHARQUOTECHARESCAPECHARFrom theAWS docs for Athenawe have this tip:Enter appropriate values for separatorChar, quoteChar, and escapeChar. The separatorChar value is a comma (,), the quoteChar value is double quotes ("), and the escapeChar value is the backslash (\).So it appears that you are supposed to uselowerCamelCaseversions of the Java fields.

As Amit mentioned, DynamoDB doesn't provide a mechanism to enable TTL on a column.That said, I can see that this could be built on top of DynamoDB.I haven't tried this, so this is simply theory, but if one wanted to TTL a column;Imagine two tables:
a. Your current table you wish to TTL a column (Lets call this Original)
b. A new table your TTL logic will be based off (Lets call this TTL Table)Create a new TTL table, to trigger the column based TTLs off, and associate a Lambda to this.Tie a Lambda trigger to the Original table, you wish to TTL a column, and on every event, Perform a PUT operation on the TTL Table with the following data:
a. The Primary Key from the original table
b. TTL time
c. Attribute to remove from original tableWhen the TTL expires on the TTL table, you can trigger the removal of the column from the original table, based on the Primary Key, and the Attribute.It would seem possible to build, but I would recommend testing it thoroughly.HTHShareFollowansweredJan 1, 2018 at 12:02Abhaya ChauhanAbhaya Chauhan1,2391111 silver badges88 bronze badges1Thanks Abhaya for the answer.

After reading DynamoDB(DDB) doc, I know there is only builtin TTL for item/row. Then I wonder if there is a convenient way to implement TTL for column? When a TTL expires, the value in the column of an item (if any) will be eliminated. The general use case is that some field of a row is of limited durability. TTL ensures robustness of a program's business logic.I learnt that there is DDB trigger using AWS lambda but the limitation is that AWS lambda only deals with DDB stream (of item update). If an item sits silently in the table for a long time, the column of interest in the item will not be erased after an expected TTL. Please correct me if I miss something.I know that one can add a job to poll DDB periodically. I don't like the idea as that is a significant burden for DDB as the job needs to scan DDB (index) and the scan could be time consuming depending on the size of a DDB table of interest and is a source of data contention.Regards,Jun

I dont see a method in theCognitoUserobject to do this on my end with the loginResult from fb. No user is getting created in the userpool upon fb auth.2) Assuming a fb user were to be created in my pool, how would I call getSessionInBackground without the password?

I don't believe so.

</Error>.I test this through the PostMan tool putting the headers and direct request through Chrome browser and still getting the same error.I have use the correct Cloudfront Key Pair and correct resource URL. My objects are private and cloudfront have access to it. Is there any thing else that i need to work on to get this working?

What I recall when being smacked by this same problem a while ago...When using a Lambda or HTTP proxy integration, you need to specify at a minimum theAccess-Control-Allow-Originheader the in your lambda's response. You may have specify additional (don't have any code handy at the moment). I do recall this message to be somewhat misleading, and that testing from the management console works because it's not really using CORS because of how the console executes the tests.Have a look at the last section in:Enabling CORS for a REST API resourceexports.handler = async (event) => {
const response = {
statusCode: 200,
headers: {
"Access-Control-Allow-Headers" : "Content-Type",
"Access-Control-Allow-Origin": "https://www.example.com",
"Access-Control-Allow-Methods": "OPTIONS,POST,GET"
},
body: JSON.stringify('Hello from Lambda!'),
};
return response;
};You need to replaceAccess-Control-Allow-Originwith the host name used by your client app. As a quick test use*, but don't go to production as that defeats the purpose of CORS.ShareFollowansweredJun 8, 2020 at 18:41Jason ArmstrongJason Armstrong1,1541010 silver badges1919 bronze badgesAdd a comment|

I have a problem with AWS API Gateway.
I'm developing a web application with Angular 4 (using TypeScript language), but if I invoke the PUT method from the frontend,
the following error message appears:Method PUT is not allowed by Access-Control-Allow-Methods in preflight response.and it's very strange because in the AWS console the PUT method works perfectly (I did many tests directly from the API Gateway console with a stage after the deploy, and everything works well). If I go to "Actions/Enable CORS" all methods have the check, included the PUT method, and I don't explain exactly what is the problem with the API Gateway.Why do I get this error if it seems all ok in API gateway? Is there a way to change these CORS?

I don't know if this is still relevant for you, but you do need to configure the EC2MetadataCredentials as it is not in the default ProviderChain ( search for new AWS.CredentialProviderChain([ in node_loader.js in the sdk).It seems you might have an old version of aws_sdk as that code works for me:import AWS from 'aws-sdk';

Using the Node sdk for AWS, I'm trying to use the credentials and permissions given by the IAM role that is attached to the EC2 instance that my Node application is running on.According to the sdk documentation, that can be done using theEC2MetadataCredentialsclass to assign the configuration properties for the sdk.In the file that I'm using the sdk in to access a DynamoDB instance, I have the configuration code:import AWS from 'aws-sdk'
AWS.config.region = 'us-east-1'
AWS.config.credentials = new AWS.EC2MetadataCredentials({
httpOptions: { timeout: 5000 },
maxRetries: 10,
retryDelayOptions: { base: 200 }
})
const dynamodb = new AWS.DynamoDB({
endpoint: 'https://dynamodb.us-east-1.amazonaws.com',
apiVersion: '2012-08-10'
})However, when I trying to visit the web application I always get an error saying:Uncaught TypeError: d.default.EC2MetadataCredentials is not a constructorUncaught TypeError: _awsSdk2.default.EC2MetadataCredentials is not a constructorEven though that is the exact usage from the documentation! Is there something small that I'm missing?Update:Removing thecredentialsandregiondefinitions from the file result in another error that'll say:Error: Missing region|credentials in config

It appears you would like to set TTL attribute when sending OTP messages but currently Amazon SNS does not support setting TTL for any of the following:SMSSQSHTTPemail.TTL is only applicable when sending mobile push notification using any of the following platform:APNSAPNS_SandboxFCMADMBaiduWNSShareFollowansweredOct 27, 2019 at 16:12aksyumaaksyuma3,09011 gold badge1717 silver badges3232 bronze badgesAdd a comment|

I'm writing code to send an OTP message. My current parameters and publish method look as follows:params = {
Message: otpMessage,
MessageStructure: 'string',
PhoneNumber: contactNo
};
sns.publish(params, function(err, data) {
if (err) console.log(err, err.stack); // an error occurred
else console.log(data); // successful response
});How do I set the TTL attribute?

It doesn't answer OP's issue which is about being able to undertake adestroyoperation on the current terraform configuration while ensuring the given resource will exceptionally not be destroyed. I.e. destroying every resource in the config except the one in question. Your idea only prevents us from being able toterraform destroy, which is completely useless in the context of OP's post.–adamencyMay 16, 2022 at 19:203The issue is trackedhereby the way.

I'd like to retain CloudWatch logs after I spin down a bunch of resources created using terraform - which includes the CloudWatch log group. Is there a way to tellterraform destroyto spare some resources?I suppose I could manually remove CloudWatch resources from tfstate before calling destroy, doesn't seem like the right approach.

I've been trying to resolve the issue for the past 3 hours now. I have an ec2 instance that is running a tomcat application. I launched it from the eclipse using "Deploy to Elastic Beanstalk option" from aws plugin.And I have a postgreSQL RDS instance. I am able to connect to the database from the localhost but my ec2 instance can't connect. I've fixed my inbound rules in rds security group to allow all kinds of traffic in. Still no luck. Please help!Here's the screen from my rds security group on aws consoleEDIT:Here's my vpc and subnet info on ec2 instance:And on my rds instance:My security group inbound rules on ec2:

Grettings everyone,We are usingAWSasPaaSand we have a couple of microservices deployed there. We got some new requirements to use some sort of cron jobs and schedulers.For example we have the following scenarios:A user can set some rules when an event must happen. For example he wants to remove some oudated documents every Friday or once a week or every 2 daysA user can configure creating copies of some objects every day till date AI used to use Quartz before and it is the first idea that comes in my mind. I think that we can use it in AWS, cause it has RDS(with PostgreSQL for instance).But I would like to know what sort of other options can I use instead of Quartz(http://www.quartz-scheduler.org) + RDS? May be AWS has something out of the box that can do the same?What do you think abouthttp://docs.aws.amazon.com/batch/latest/userguide/what-is-batch.htmlin my case?Thank you for your time and advice :)

I think you'll have to request for "profile" or other scopes in order to get that.I recently created a related framework and it has an example of retrieving the user profile information.https://github.com/Thywis/MultiAccountOauthShareFollowansweredJun 24, 2017 at 5:06ThywisThywis1111 bronze badgeAdd a comment|

AWSCognitoDataset *dataset = [syncClient openOrCreateDataset:@"myDataSet"];
NSString *userName = [dataset stringForKey:@"name"];But still getting null as userName. If possible can you please let me know the possible way.
