Description
Test scenario:
- 9 nodes
- 1 bucket, 1 replica, full eviction
- 1B items (~1KB), 5-10% resident ratio
- 15K ops/sec (90% read, 10% update), 10% cache miss ratio (before rebalance)
- Swap rebalance of one node (172.23.96.108 -> 172.23.96.109)
I noticed this issue when I was running another test with 10TB of data. Later I realized that high latency can also be observed during a very simple test with just 1TB.
Latency on *.100 (doesn't participate in rebalance):
