Bug report

When real time processing is enabled the log file is removed on application exit

What Debezium connector do you use and what version?

Cassandra 4 connector 2.0.0.Final

What is the connector configuration?

debezium.source.commit.log.real.time.processing.enabled=true
debezium.source.commit.log.marked.complete.poll.interval.ms=2000

What is the captured database version and mode of depoyment?

Official Cassandra 4 docker image

What behaviour do you expect?

Log file should not be deleted

What behaviour do you see?

Log file is deleted

Implementation ideas (optional)

The problem resides in AbstractCassandra4CommitLogParser in process() method:

        CommitLogProcessingResult result = parse();
        enqueueEOFEvent();

The EOF event tells the QueueProcessor to delete the log file but in case of application exit it shouldn't.

So 

enqueueEOFEvent();

should be called only for specific CommitLogProcessingResult result values: OK and ERROR
