    Description

      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.
