Jeff Jirsa commented on CASSANDRA-12837:
----------------------------------------
This is not a review, but a few notes:
- 2.2.x isn't getting new features, and a feature that adds thread pool
executors probably belongs in 3.X at the newest (3.10, not 2.1/2.2/3.0).
- We have other ways of doing parallel compaction that's used by
cleanup/scrub/upgradesstables -
https://github.com/apache/cassandra/blob/f2a354763877cfeaf1dd017b84a7c8ee9eafd885/src/java/org/apache/cassandra/db/compaction/CompactionManager.java#L287
- would it be reasonable to try to utilize that, rather than building your
multi-threading and adding new executor pools?
- Why does this rely on Murmur3 partitioner? Why wouldn't it be possible with
{{RandomPartitioner}} ? Or any of the others?
- This may be less important with CASSANDRA-11218
