    Description

      Running volume test with 500M docs in 2 collections and through the run I notice the bucket doc count going up and down for no reason. As part of the run we do scale of the node which induce swap rebalance.

      From capella UI:

      From couchbase console we see some nodes have 0 docs but disk used looks ok:

      and at another time:

       

      but count should 500M as reported by query:

       

      see attached logs or https://supportal.couchbase.com/snapshot/b5caa76a487086a163535edf0b00639c::1
