Prerequisites

The following are required to run query source connector:

• kubemq cluster
• kubemq-targets deployment

Configuration

Query source connector configuration properties:

Properties Key	Required	Description	Example
address	yes	kubemq server address (gRPC interface)	kubemq-cluster:50000
client_id	no	set client id	"client_id"
auth_token	no	set authentication token	jwt token
channel	yes	set channel to subscribe
group	no	set subscriber group
sources	no	set how many query sources to subscribe	1
auto_reconnect	no	set auto reconnect on lost connection	"false", "true"
reconnect_interval_seconds	no	set reconnection seconds	"5"
max_reconnects	no	set how many times to reconnect	"0"

Example:

bindings:
  - name: kubemq-query-elastic-search
    source:
      kind: kubemq.query
      name: kubemq-query
      properties:
        address: "kubemq-cluster:50000"
        client_id: "kubemq-query-elastic-search-connector"
        auth_token: ""
        channel: "query.elastic-search"
        group:   ""
        source: "1"
        auto_reconnect: "true"
        reconnect_interval_seconds: "1"
        max_reconnects: "0"
    target:
      kind: stores.elastic-search
      name: target-elastic-search
      properties:
        urls: "http://localhost:9200"
        username: "admin"
        password: "password"
        sniff: "false"
