> Also, would it be a performance-wise concern when people run rebalance with `minAvailableReplicas=0` on a peer enabled table now, since we'll have to fetch zk metadata "`numSegments`" times? Do we know how much the overhead is here? There will be more calls to fetch the ZK metadata for sure which will add latency and also hit ZK more often. We're accessing ZK metadata for multiple reasons during rebalance, and since it's an operation that we expect to take time, IMO it should be okay from the latency perspective. The additional ZK access may be more concerning, I'm not sure if there is a good way around that though. any thoughts or recommendations @noob-se7en @J-HowHuang ? I was thinking if there is a way to cache this somewhere or if it is already cached such that we can use it? -- This is an automated message from the Apache Git Service.
