      Hi all,

      I'm using Debezium Postgres connector, I enabled the heartbeat action, which includes

      • create heartbeat table if not exist
      • insert a record into the table

      This works fine for all existing DB with regular traffic.


      However I noticed when the DB is empty/no traffic, the heartbeat action will not trigger at all after redeplolyment of the connector. Unless I manually insert a record into the heartbeat table, the heartbeat table started to action. 


      This has become an issue as if the heartbeat action is not working. even if the DB is empty, the replication slots still got filled up due to system logs.
