A problem in compaction reevaluation can cause the SSTable set to be left uncompacted for indefinite amount of time, potentially causing space and read amplification to be suboptimal.
Two revaluation problems are being fixed, one after off-strategy compaction ended, and another in compaction manager which intends to periodically reevaluate a need for compaction.
