Re: Compaction throughput vs. number of compaction threads?

Hi, The compaction throughput is indeed shared by all compactors. I would not advise to go below 8MB/s per compactor as slowing down compactions put more pressure on the heap. When tuning compaction, the first thing to do is evaluate the maximum throughput your disks can sustain without

Compaction throughput vs. number of compaction threads?
