Hi all, Yesterday I put a lot of blobs into Cassandra and it created many, probably compaction, pending tasks (few hundreds according to Ops Center). On all nodes all pending tasks were eventually processed, but on one problematic, I see no related activity. Problematic node seems to be responsive and no errors in logs. What can be the reason?
Cassandra ver: multiple versions on 14 nodes (2.0.8 and 2.0.9) OpsCenter ver: 4.1.2 Compaction type: leveled (we had capacity issues with size-tiered). To process pending task as fast as possible, I temporary changed compaction_throughput_mb_per_sec to 0 on this specific node. It helps, but only when compaction running, and currently pending tasks are not being processed. Thanks, Pavel
