      Description

      We've heard reports of auto-compactor compacting even already compacted vbuckets.

      This may happen for example during rebalance where lots of bulk changes happen in just few vbuckets. We should be compacting just those vbuckets. But we currently compact everything, causing somewhat quadratic behavior on heavier rebalances.

      "compactor is unable to catch up during XDCR" bug somewhere may be "it" or just related.

        I'd like to consider this for 2.0.1. I don't have large scale runs data yet.

        Fix went into master http://review.couchbase.org/#/c/24365/

        I think having it in 2.0.1 will help.
