Prerequisites

The following are required to run the query target connector:

• kubemq cluster
• kubemq-sources deployment

Configuration

Query target connector configuration properties:

Properties Key	Required	Description	Example
address	yes	kubemq server address (gRPC interface)	kubemq-cluster-grpc.kubemq.svc.cluster.local:50000
client_id	no	set client id	"client_id"
auth_token	no	set authentication token	JWT token
channel	no	set send request default channel	"queries"
timeout_seconds	no	sets query request default timeout (600 seconds)	"10"

Example:

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: ""
        channel: "queries"
        timeout_seconds: "10"
