Alex Deparvu commented on CASSANDRA-14987:
------------------------------------------
Trying to give this a go, some initial work can be seen
[here|https://github.com/stillalex/cassandra/commit/ac5fe544527c43645815118aabdca7d59d90ba32].
If I understand the issue, it would be as simple as using the
{{CompactionInfo.Holder#isStopRequested}} to distinguish an interrupted
compaction.
I think the current code is not enough, we might also need to update the
'compaction_history' table?
I'm not yet sure, but I think the {{CompactionHistory}} stats is based on this
info, so ideally this would also reflect the interrupted state.

>
> To be able to track how often we interrupt compactions (for example when
> starting anticompactions) we should add a few metrics;
> * number of interrupted compactions
> * number of bytes written by interrupted compactions
> We currently count an interrupted compaction as completed, which should
> change with this
