| ---------------- | -------- | ------------------------------------------------ | -------------------------------------------------- |
| address          | yes      | kubemq server address (gRPC interface)           | kubemq-cluster-grpc.kubemq.svc.cluster.local:50000 |
| client\_id       | no       | set client id                                    | "client\_id"                                       |

| dynamic\_mapping | no       | set dynamic channel mapping per source           | "false"                                            |
| timeout\_seconds | no       | sets query request default timeout (600 seconds) | "10"                                               |

Example:

```yaml
bindings:
  - name:  query-binding 
    properties: 
      log_level: error
      retry_attempts: 3
      retry_delay_milliseconds: 1000
      retry_max_jitter_milliseconds: 100
      retry_delay_type: "back-off"
      rate_per_second: 100
    source:
      kind: http
      name: http-get-source
      properties:
        "methods": "get"
        "path": "/query"
    target:
      kind: kubemq.query # Sources kind
      name: query-target 
      properties: 
        address: "kubemq-cluster-grpc.kubemq.svc.cluster.local:50000"
        client_id: "cluster-a-query-connection"
        auth_token: ""
