title: Processing S3 events in order with Lambda
body: <p>I am setting up an S3 bucket. In this S3 bucket, data is going to be written by an external process.</p>
  <p>I am setting up an AWS Lambda that would be triggered when an object in S3 gets created/updated and would process and store the data in RDS.</p>
  <p>Here my question is as follows:</p>
  <p>If objects get written too fast on s3, there is a possibility for multiple Lambda functions
  to get triggered simulatenously.</p>
  <p>So, in this case, is there any chance for the objects to be processed not in the order they
  are written to the S3 bucket?</p>
  <p>If the answer to the above question is yes, then with Lambda, I have to push the payload to
  FIFO SQS and set up a listener to process the payload to store the data into RDS finally.</p>
