Chapter 50. Message Timestamp Router Action
Chapter 50. Message Timestamp Router Action Update the topic field as a function of the original topic name and the record's timestamp field. 50.1. Configuration Options The following table summarizes the configuration options available for the message-timestamp-router-action Kamelet: Property Name Description Type Default Example timestampKeys * Timestamp Keys Comma separated list of Timestamp keys. The timestamp is taken from the first found field. string timestampFormat Timestamp Format Format string for the timestamp that is compatible with java.text.SimpleDateFormat. string "yyyyMMdd" timestampKeyFormat Timestamp Keys Format Format of the timestamp keys. Possible values are 'timestamp' or any format string for the timestamp that is compatible with java.text.SimpleDateFormat. In case of 'timestamp' the field will be evaluated as milliseconds since 1970, so as a UNIX Timestamp. string "timestamp" topicFormat Topic Format Format string which can contain 'USD[topic]' and 'USD[timestamp]' as placeholders for the topic and timestamp, respectively. string "topic-USD[timestamp]" Note Fields marked with an asterisk (*) are mandatory. 50.2. Dependencies At runtime, the message-timestamp-router-action Kamelet relies upon the presence of the following dependencies: mvn:org.apache.camel.kamelets:camel-kamelets-utils:1.0.0.fuse-800048-redhat-00001 camel:jackson camel:kamelet camel:core 50.3. Usage This section describes how you can use the message-timestamp-router-action . 50.3.1. Knative Action You can use the message-timestamp-router-action Kamelet as an intermediate step in a Knative binding. message-timestamp-router-action-binding.yaml apiVersion: camel.apache.org/v1alpha1 kind: KameletBinding metadata: name: message-timestamp-router-action-binding spec: source: ref: kind: Kamelet apiVersion: camel.apache.org/v1alpha1 name: timer-source properties: message: "Hello" steps: - ref: kind: Kamelet apiVersion: camel.apache.org/v1alpha1 name: message-timestamp-router-action properties: timestampKeys: "The Timestamp Keys" sink: ref: kind: Channel apiVersion: messaging.knative.dev/v1 name: mychannel 50.3.1.1. Prerequisite Make sure you have "Red Hat Integration - Camel K" installed into the OpenShift cluster you're connected to. 50.3.1.2. Procedure for using the cluster CLI Save the message-timestamp-router-action-binding.yaml file to your local drive, and then edit it as needed for your configuration. Run the action by using the following command: oc apply -f message-timestamp-router-action-binding.yaml 50.3.1.3. Procedure for using the Kamel CLI Configure and run the action by using the following command: kamel bind timer-source?message=Hello --step message-timestamp-router-action -p "step-0.timestampKeys=The Timestamp Keys" channel:mychannel This command creates the KameletBinding in the current namespace on the cluster. 50.3.2. Kafka Action You can use the message-timestamp-router-action Kamelet as an intermediate step in a Kafka binding. message-timestamp-router-action-binding.yaml apiVersion: camel.apache.org/v1alpha1 kind: KameletBinding metadata: name: message-timestamp-router-action-binding spec: source: ref: kind: Kamelet apiVersion: camel.apache.org/v1alpha1 name: timer-source properties: message: "Hello" steps: - ref: kind: Kamelet apiVersion: camel.apache.org/v1alpha1 name: message-timestamp-router-action properties: timestampKeys: "The Timestamp Keys" sink: ref: kind: KafkaTopic apiVersion: kafka.strimzi.io/v1beta1 name: my-topic 50.3.2.1. Prerequisites Ensure that you've installed the AMQ Streams operator in your OpenShift cluster and created a topic named my-topic in the current namespace. Make also sure you have "Red Hat Integration - Camel K" installed into the OpenShift cluster you're connected to. 50.3.2.2. Procedure for using the cluster CLI Save the message-timestamp-router-action-binding.yaml file to your local drive, and then edit it as needed for your configuration. Run the action by using the following command: oc apply -f message-timestamp-router-action-binding.yaml 50.3.2.3. Procedure for using the Kamel CLI Configure and run the action by using the following command: kamel bind timer-source?message=Hello --step message-timestamp-router-action -p "step-0.timestampKeys=The Timestamp Keys" kafka.strimzi.io/v1beta1:KafkaTopic:my-topic This command creates the KameletBinding in the current namespace on the cluster. 50.4.
