Hi,

To process the CDC commitLogs, it requires a separate Daemon process, Carl has a Daemon example here: CASSANDRA-11575.

Does it make sense to integrate it into Cassandra? So the user doesn't have to manage another JVM on the same box. Then provide an ITrigger like interface (https://github.com/apache/cassandra/blob/trunk/src/java/org/apache/cassandra/triggers/ITrigger.java#L49) to process the data.

Or maybe provide an interface option to handle the CDC commitLog in SegmentManager(https://github.com/apache/cassandra/blob/trunk/src/java/org/apache/cassandra/db/commitlog/CommitLogSegmentManagerCDC.java#L68).

Any comments? If it make sense, I could create a JIRA for that.

Thanks,
Jay
