Description

As example, it will be possible to use a Kamelet to create a[ Debezium Source Connectors |https://camel.apache.org/components/latest/debezium-summary.html]

 Definition

Definite DBZ MySQL Connector named debezium-mysql-source.kamelet.yaml

apiVersion: camel.apache.org/v1alpha1
kind: Kamelet
metadata:
  name: debezium-mysql-source
  annotations:
    camel.apache.org/kamelet.support.level: "Preview"
    // other ...
  labels:
    camel.apache.org/kamelet.type: "source"
spec:
  definition:
    title: "Debezium MySQL"
    required:
      - databaseServerId
      - databaseServerName
// others...
    properties:
      databaseServerId:
        //...
      databaseServerName:
       //...
      // others ...
  dependencies:
   // ...
  flow:
    from:
      uri: debezium-mysql:{{databaseServerName}}
      parameters:
        databaseServerName: "{{databaseServerName}}"
        databaseServerId: "{{databaseServerId}}"
// others...
      steps:
        - to: "kamelet:sink"

As example:

from("debezium-mysql:dbz-test-1?databaseServerName=dbz-test-1&databaseServerId=5401&...")
.log("Event received from Debezium : ${body}")

Using the Kamelet example above, the message property can then be given:
1. by setting a URI Param named databaseServerName and databaseServerId
OR
2. by setting the property camel.kamelet.debezium-mysql-source.source.databaseServerName and camel.kamelet.debezium-mysql-source.source.databaseServerId

It will be very useful when build this with camel-kamelets projects.
For example create a YAML file like the following one:

apiVersion: camel.apache.org/v1alpha1
kind: KameletBinding
metadata:
  name: debezium-mysql-source-binding
spec:
  source:
    ref: 
      kind: Kamelet
      apiVersion: camel.apache.org/v1alpha1
      name: debezium-mysql-source
    properties:
      databaseServerId: 5401
      databaseServerName: "dbz-test-1" 
      // difference !! we can't defined includeQuery and includeSchemaChanges  in  source YAML above(debezium-mysql-source.kamelet.yaml)
      includeQuery: "true"
      includeSchemaChanges:"false"
      ....

The includeQuery and includeSchemaChanges may be affected as same as uri params like databaseServerName in runtime env
