Yuki Morishita commented on CASSANDRA-4100:
-------------------------------------------
OK, so static Throttle is fine here since one compaction_throughput_mb_per_sec
is used for all compactions. Then, do we need to divide that by number of
active compactions? I'm referring the code inside the implementation of
ThroughputFunction:
{code}
totalBytesPerMS / Math.max(1,
CompactionManager.instance.getActiveCompactions());
{code}
> Make scrub and cleanup operations throttled
