Description

Consecutive requests to the PUT /connectors/<name>/resume endpoint will cause the Connector to be restarted. This is a little wasteful and conflicts with the idempotent nature of that endpoint. We can tweak the MemoryConfigBackingStore and KafkaConfigBackingStore classes to not invoke the onConnectorTargetStateChange method of their ConfigUpdateListener instance if they pick up a new target state that matches the current target state of the connector.
