Change subject: [master] KUDU-3061 support auto rebalance tablet leaders across TServers ...................................................................... Patch Set 11: (1 comment) Thanks your crs. http://gerrit.cloudera.org:8080/#/c/18454/10//COMMIT_MSG Commit Message: http://gerrit.cloudera.org:8080/#/c/18454/10//COMMIT_MSG@10 PS10, Line 10: to load skew on some nodes. > I'm not sure I can parse this. Could you rephrase or clarify on this? Ok, I can rewrite some sentences. The work can start without the load data, it can be supported by results of the qualitative analysis. 1. ScanRequests default is LeaderOnly, mostly , so the scan load is positive correlation with leader numbers. This is main reason. 2. For write requests, leaders receive write request, followers receive appendEntries(kudu is UpdateConsensus), the flow of processing is different , which maybe cause imbalanced load. The quantity income of lauto eader rebalancer can be solved by some study if needed. -- 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: 11 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: Yingchun Lai <[email protected]> Gerrit-Reviewer: Yuqi Du <[email protected]> Gerrit-Comment-Date: Wed, 01 Jun 2022 02:47:30 +0000 Gerrit-HasComments: Yes
