Description
KV-only rebalance test, 3 -> 4 nodes, 1 bucket x 100M x 2KB, 10K mixed ops/sec
We recently enabled UPR-based rebalance by default. As result we are > 20x slower now (20 minutes vs. 460 minutes).
Most importantly there is inconsistency in backfilling speed, some movements take 20-30 minutes:
