Hi, We have a cluster which we've recently moved to use LeveledCompactionStrategy. We were experiencing some disk space issues, so we added two additional nodes temporarily to aid compaction. Once the compaction had completed on all nodes, we decommissioned the two temporary nodes.
All nodes now have a high number of pending tasks which isn't dropping - they're remaining approximately static. There are constantly compaction tasks running, but when they complete, the pending tasks number doesn't drop. We've set the compaction rate limit to 0, and increased the number of compactor threads until the I/O utilisation is at maximum, but neither of these have helped. Any suggestions? Cheers, -- Russ Garrett r...@garrett.co.uk
