| * The target state of a connector is its desired state as indicated by the user |
| * through interaction with the REST API. When a connector is first created, its |
| * target state is "STARTED." This does not mean it has actually started, just that |
| * the Connect framework will attempt to start it after its tasks have been assigned. |
| * After the connector has been paused, the target state will change to PAUSED, |
| * and all the tasks will stop doing work. |
| * |
| * Target states are persisted in the config topic, which is read by all of the |
| * workers in the group. When a worker sees a new target state for a connector which |
| * is running, it will transition any tasks which it owns (i.e. which have been |
| * assigned to it by the leader) into the desired target state. Upon completion of |
| * a task rebalance, the worker will start the task in the last known target state. |
