---------------------------------------------------------------
[~e.dimitrova] Thanks for the report. This patch allows ZCS for size-tiered
compaction which is used by the test and the test log showed that the file is
indeed received via ZCS...

Transient replica repair is removing the received file and it's doing it faster
on ZCS sstable than non-ZCS sstable..

> Improve zero-copy-streaming containment check by using file sections
> --------------------------------------------------------------------
>
> Key: CASSANDRA-15657
> URL: https://issues.apache.org/jira/browse/CASSANDRA-15657
> Project: Cassandra
> Issue Type: Improvement
> Components: Legacy/Streaming and Messaging
> Reporter: ZhaoYang
> Assignee: ZhaoYang
> Priority: Normal
> Fix For: 4.0
>
>
> Currently zero copy streaming is only enabled for leveled-compaction strategy
> and it checks if all keys in the sstables are included in the transferred
> ranges.
> This is very inefficient. The containment check can be improved by checking
> if transferred sections (the transferred file positions) cover entire sstable.
> I also enabled ZCS for all compaction strategies since the new containment
> check is very fast..
