Hi all, I have a small cluster (2 nodes RF 2) running with C* 2.0.6 on I2 Extra Large (AWS) with SSD disk, the nodetool tpstats shows many MemtablePostFlusher pending and FlushWriter All time blocked.
The two nodes have the default configuration. All CF use size-tiered compaction strategy. There are 10 times more reads than writes (1300 reads/s and 150 writes/s). ubuntu@node1 :~$ nodetool tpstats Pool Name Active Pending Completed Blocked All time blocked MemtablePostFlusher 1 1158 159590 0 0 FlushWriter 0 0 11568 0 1031 ubuntu@node1:~$ nodetool compactionstats pending tasks: 90 Active compaction remaining time : n/a ubuntu@node2:~$ nodetool tpstats Pool Name Active Pending Completed Blocked All time blocked MemtablePostFlusher 1 1020 50987 0 0 FlushWriter 0 0 6672 0 948 ubuntu@node2:~$ nodetool compactionstats pending tasks: 89 Active compaction remaining time : n/a I think there is something wrong, thank you for your help.
