Example Requests

  • To enable Smart Connect for pay-per-use instances using new flavors, set the number of connectors to 2.

    POST https://{endpoint}/v2/{project_id}/instances/{instance_id}/connector
    
    {
      "node_cnt" : 2
    }
  • To enable Smart Connect for pay-per-use instances using old flavors, set the size of connectors to 100 MB and the number of them to 2.

    POST https://{endpoint}/v2/{project_id}/instances/{instance_id}/connector
    
    {
      "specification" : "100MB",
      "node_cnt" : 2,
      "spec_code" : "kafka.c3.mini.connector"
    }

Example Responses

Status code: 200

Successful.
