Kurt Greaves commented on CASSANDRA-10540:
------------------------------------------

[~krummas] We didn't run into any issues after applying the repair patch from CASSANDRA-13938. We'll probably look at doing a few more tests with repair to measure repair timings with RACS enabled. Let me know if there's anything you need help with to get this in by 4.0.

> Broken out from CASSANDRA-6696, we should split sstables based on ranges during compaction.
> Requirements;
> * dont create tiny sstables - keep them bunched together until a single vnode is big enough (configurable how big that is)
> * make it possible to run existing compaction strategies on the per-range sstables
> We should probably add a global compaction strategy parameter that states whether this should be enabled or not.
