The furthest we got to a reference daemon was Carl's work on 11575. Hasn't
been prioritized since then since the interface refactors were the lion's
share of the necessary complexity to allow people to build off the feature.
As for any follow-up work,

Thanks Josh for your response. I agree that it may cause the JVM
unstable if that feature is enabled. (we may still want to try that out
internally and do some perf/stress tests, will share more information if
we have the results. If you have any suggestions on testing, please let
me know.)

The primary reason I avoided integrating a daemon into the Cassandra
process was the increase in heap pressure and further muddying of the
profile of heap usage. We've already seen that mixing read/write,
compaction, streaming, and repair in the same JVM causes a nasty mix of
allocation patterns th
No. It's going to have Cassandra to manage the CDC logs, instead of
having another daemon process to handle that.
Here is CDC design JIRA: CASSANDRA-8844. The pain point is to develop
and manage the daemon. If they're integrated, it's going to be easier to
manage and monitor that.
Thanks,
Ja
Is it for testing purpose?
