Summary: Improve concurrency in CompactionStrategyManager
Key: CASSANDRA-10099
URL: https://issues.apache.org/jira/browse/CASSANDRA-10099
Project: Cassandra
Issue Type: Improvement
Reporter: Yuki Morishita
Fix For: 3.x
Continue discussion from CASSANDRA-9882.
CompactionStrategyManager(WrappingCompactionStrategy for <3.0) tracks SSTable
changes mainly for separating repaired / unrepaired SSTables (+ LCS manages
level).
This is blocking operation, and can lead to block of flush etc. when
determining next background task takes longer.
Explore the way to mitigate this concurrency issue.
