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 |
| |
| 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.

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.yamlfile 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.yamlfile 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.
