-----------------------------------------
Component/s: Compaction
> Change the way LCS major compaction works
> -----------------------------------------
>
> Key: CASSANDRA-11817
> URL: https://issues.apache.org/jira/browse/CASSANDRA-11817
> Project: Cassandra
> Issue Type: Improvement
> Components: Compaction
> Reporter: Marcus Eriksson
> Priority: Major
> Labels: lcs
> Fix For: 4.x
>
>
> Currently we start writing in L1 and then continue in L2 once L1 is full, it is probably better to pick a high level and write all sstables to that level.
> I suspect that the end result will be basically the same without a bunch of pointless single-sstable compactions into an empty space in level+1
