Few questions on compaction behavior (with CB Server 5.1 & 5.5):
1.If we desire to kick off compaction manually, thru couchbase-cli – should the compaction be kicked off on “each node of the cluster” or just once from any node of the cluster?
2. What happens if a compaction op is kicked off, while a previous compaction is still running? Is it safe/non-intrusive OR must we ensure to check if a compaction is currently running before we kick off a new one?
3. If so, how to detect a. if compaction is currently running; b. the progress/stats of the currently running compaction job?
