      Description

      Setup a cluster as above.
      Create 2 views per bucket.
      Run time : 10 hour+

      Seeing uneven compaction/ high doc fragmentation across the nodes. ( Screenshot attached below)

      Seeing very high swap on these nodes as well ( Screenshot below)

      • Indexing / Compaction is running continuosly, but never completes.

      Adding logs.

      • Does this high doc fragmentation(70-80 percent) indicate that compaction did not work as expected?
        Is this something we ve seen before/ know of?

      Please let me know if you need any other system information on this.
