Description

We use confluent3.0 package+Debezium for steaming mysql data into Kafka.

How ever we had some minor issues with mysql and had to restart mysql servers. After the restart of mysql server, KC stops(this is expected, its there on DBZ docs).

We restarted KC, later kaka-connect starts without any error, But it will not stream the data into Kafka.

We can see following like in logs and connect Just sits there, without committing any thing to kafka.

INFO Source task WorkerSourceTask

{id=XXXXXX}

finished initialization and start (org.apache.kafka.connect.runtime.WorkerSourceTask:138)
