I'm not sure what the state of documentation is for Change Data Capture.
The best docs may be the design document linked in the comments on the
ticket, which I think is current.

I believe this sounds like a CDC use case. Trust the discussion on the
ticket more than my summary here, but: the changes in CASSANDRA-8844 expose
some previously-internal commitlog-reading behavior. This allows users to
implement their own code to consume changes to commitlogs on tables where
the feature is enabled.

Also any update on the tentative release of this branch?

The patch is currently under review, but currently targeting a 3.8 release.
3.8 should be released in the next two months as part of the tick-tock
release schedule.
