> 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..
