Change subject: [master] KUDU-3061 support auto rebalance tablet leaders across TServers ...................................................................... Patch Set 19: (1 comment) I didn't really look into the codes because I'd like to understand the design consideration and the use of algorithm first. Here are some questions I don't know much about: - Is this leader rebalance task only transfer the leadership between replicas of the same tablet? Or it also copy replicas from one server to another? - Do we have to rebalance replicas in a cluster before we run this leader rebalance task? - Can we finally get a fully balanced cluster in all cases? If you already have a design document about this issue, can you share it so wen can discuss about the details. http://gerrit.cloudera.org:8080/#/c/18454/19//COMMIT_MSG Commit Message: http://gerrit.cloudera.org:8080/#/c/18454/19//COMMIT_MSG@14 PS19, Line 14: Two reasons of load skew: Besides clarify why we need to balance leader replicas across TServers, it would be better if you can show the skew of leaders in a cluster before and after run the balance task. -- To view, visit http://gerrit.cloudera.org:8080/18454 To unsubscribe, visit http://gerrit.cloudera.org:8080/settings Gerrit-Project: kudu Gerrit-Branch: master Gerrit-MessageType: comment Gerrit-Change-Id: Ibfb60d8759a93b6a19238637c27df4f6b1cac918 Gerrit-Change-Number: 18454 Gerrit-PatchSet: 19 Gerrit-Owner: Yuqi Du <[email protected]> Gerrit-Reviewer: Alexey Serbin <[email protected]> Gerrit-Reviewer: Andrew Wong <[email protected]> Gerrit-Reviewer: Kudu Jenkins (120) Gerrit-Reviewer: Tidy Bot (241) Gerrit-Reviewer: Yifan Zhang <[email protected]> Gerrit-Reviewer: Yingchun Lai <[email protected]> Gerrit-Reviewer: Yuqi Du <[email protected]> Gerrit-Comment-Date: Sun, 03 Jul 2022 16:17:30 +0000 Gerrit-HasComments: Yes
