      What is the captured database version and mode of deployment?

      7.4, on-premise

      What behavior do you expect?

      No initial snapshot after a connector restart.

      What behavior do you see?

      Initial snapshot after every connector restart.

      Do you see the same behaviour using the latest released Debezium version?

      (Ideally, also verify with latest Alpha/Beta/CR version)

      Yes.

      Do you have the connector logs, ideally from start till finish?

      (You might be asked later to provide DEBUG/TRACE level log)

      Not yet.

      How to reproduce the issue using our tutorial deployment?

      Just restart the connector using REST API or Confluent Control Center.
