>
> IndexSummaryRedistribution is a compaction task and as such extends Holder
> and supports cancelation by throwing a CompactionInterruptedException. The
> issue is that IndexSummaryRedistribution tries to use transactions, but
> mutates the sstable in-place; transaction is unable to roll back.
> This would be fine (only updates summary) if it wasn’t for the fact the task
> attempts to also mutate the two metrics liveDiskSpaceUsed and
> totalDiskSpaceUsed, since these can’t be rolled back any cancelation could
> corrupt these metrics.
