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)

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.

System Testing : Uneven compaction + Very high swap, over a cluster, some nodes have much higher (70 percent ) fragmentation than others.
