== Configuration Options

The following table summarizes the configuration options available for the `message-timestamp-router-action` Kamelet:
[width="100%",cols="2,^2,3,^2,^2,^3",options="header"]
|===
| Property| Name| Description| Type| Default| Example
| *timestampKeys {empty}* *| 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 '$[topic]' and '$[timestamp]' as placeholders for the topic and timestamp, respectively.| string| `"topic-$[timestamp]"`| 
|===

NOTE: Fields marked with ({empty}*) are mandatory.

== Usage

This section summarizes how the `message-timestamp-router-action` can be used in various contexts.

=== Knative Action

The `message-timestamp-router-action` Kamelet can be used as intermediate step in a Knative binding.

.message-timestamp-router-action-binding.yaml
[source,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: InMemoryChannel
      apiVersion: messaging.knative.dev/v1
      name: mychannel

----
Make sure you have xref:latest@camel-k::installation/installation.adoc[Camel K installed] into the Kubernetes cluster you're connected to.

Save the `message-timestamp-router-action-binding.yaml` file into your hard drive, then configure it according to your needs.

You can run the action using the following command:

[source,shell]
----
kubectl apply -f message-timestamp-router-action-binding.yaml
----

==== *Binding to Knative using the Kamel CLI:*

The procedure described above can be simplified into a single execution of the `kamel bind` command:

[source,shell]
----
kamel bind timer-source?message=Hello --step message-timestamp-router-action -p "step-0.timestampKeys=The Timestamp Keys" channel/mychannel
----

This will create the KameletBinding under the hood and apply it to the current namespace in the cluster.

=== Kafka Action

The `message-timestamp-router-action` Kamelet can be used as intermediate step in a Kafka binding.

.message-timestamp-router-action-binding.yaml
[source,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

----

Ensure that you've installed https://strimzi.io/[Strimzi] and created a topic named `my-topic` in the current namespace.
Make also sure you have xref:latest@camel-k::installation/installation.adoc[Camel K installed] into the Kubernetes cluster you're connected to.

Save the `message-timestamp-router-action-binding.yaml` file into your hard drive, then configure it according to your needs.

You can run the action using the following command:

[source,shell]
----
kubectl apply -f message-timestamp-router-action-binding.yaml
----

==== *Binding to Kafka using the Kamel CLI:*

The procedure described above can be simplified into a single execution of the `kamel bind` command:

[source,shell]
----
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 will create the KameletBinding under the hood and apply it to the current namespace in the cluster.
