Re: decommission mode with background compactors running

Streaming will grab a reference to the sstables so even if compacted they won’t be deleted until streamed - it’s safe as-is in terms of correctness, but may cause a temporary increase in disk usage as new writes happen and sstables are compacted together but old data files can’t be removed.

decommission mode with background compactors running

2017-10-04 Thread Cogumelos Maravilha
Hi list, I've decommission a node but in the background with nodetool status I've checked and there was 4 compactors running and simultaneously the SSTables sent to other nodes. Is this safe or we should disable all background process before decommission like: nodetool disableautocompaction
