REST API

  • PATCH /connectors/{name}/config - patch the configuration parameters for a specific connector, where null values in the JSON body indicates removing of the key from the final configuration
  • GET /connectors/{name}/status - get current status of the connector, including if it is running, failed, paused, etc., which worker it is assigned to, error information if it has failed, and the state of all its tasks
  • GET /connectors/{name}/tasks - get a list of tasks currently running for a connector along with their configurations
    • -
  • GET /connectors/{name}/tasks-config - get the configuration of all tasks for a specific connector. This endpoint is deprecated and will be removed in the next major release. Please use the GET /connectors/{name}/tasks endpoint instead. Note that the response structures of the two endpoints differ slightly, please refer to the OpenAPI documentation for more details
  • GET /connectors/{name}/tasks/{taskid}/status - get current status of the task, including if it is running, failed, paused, etc., which worker it is assigned to, and error information if it has failed
  • PUT /connectors/{name}/pause - pause the connector and its tasks, which stops message processing until the connector is resumed. Any resources claimed by its tasks are left allocated, which allows the connector to begin processing data quickly once it is resumed.
  • PUT /connectors/{name}/stop - stop the connector and shut down its tasks, deallocating any resources claimed by its tasks. This is more efficient from a resource usage standpoint than pausing the connector, but can cause it to take longer to begin processing data once resumed. Note that the offsets for a connector can be only modified via the offsets management endpoints if it is in the stopped state
