Maxwell Guo commented on CASSANDRA-18998:
-----------------------------------------
This may have something to do with me. Initially, I was supposed to do this
with another Netflix classmate, and then spit out the data through the sidecar,
but it seemed that there was no progress in the follow-up.And sidecar does not
have a release version either

> Key: CASSANDRA-18998
> URL: https://issues.apache.org/jira/browse/CASSANDRA-18998
> Project: Cassandra
> Issue Type: Improvement
> Components: Feature/Change Data Capture
> Reporter: Stefen Hillman
> Assignee: Dinesh Joshi
> Priority: Normal
>
> It looks like there was originally a plan to expose change data externally
> via CQL for any client to consume, as noted under Design Options #4 on the
> original design document:
> [https://docs.google.com/document/d/1ZxCWYkeZTquxsvf5hdPc0fiUnUHna8POvgt6TIzML4Y/edit?usp=sharing.]
>
> It appears that this was ultimately not implemented. Is there a plan to
> improve CDC in the future with this functionality? The current implementation
> is tedious to use - you have to write a local agent that lives on every
> single c* node and then implement the Apache-provided CommitLogReader in
> order to parse the files. On top of that, it makes deduplication and ordering
> basically impossible if there isn't an inherently ordered property.
