Change subject: KUDU-3767 Add global leader awareness to auto leader rebalancer (Part 2) ...................................................................... Patch Set 1: (1 comment) http://gerrit.cloudera.org:8080/#/c/24476/1//COMMIT_MSG Commit Message: http://gerrit.cloudera.org:8080/#/c/24476/1//COMMIT_MSG@7 PS1, Line 7: Add global leader awareness to auto leader rebalancer (Part 2) Thanks for working on this! I have a couple of questions regarding auto leader re-balancer: 1. With all the patches including KUDU-3767, KUDU-3497 and KUDU-3390, is it possible that we can have an uneven distribution of leader replicas per table and an even distribution of leader replicas for the whole cluster? As an example, in a 1 master x 3 tservers and 10 tables (RF=3) setup, table1 has 9 tablets and tserver1 is hosting 7 leader replicas, tserver2 is hosting 2 leader replicas and tserver3 is hosting no leader replica for table1. However, overall leader replica distribution is even across all three tservers. 2. If answer to above question is yes, is there a way to prioritize even distribution of leader replicas for a specific table even if that means imbalance in global leader replica distribution? I am asking this because there could be a use case where a few tables cater to more workload compared to the rest of the tables. In such a scenario, if globally even distribution of leader replicas is achieved but there is an uneven distribution of leader replicas for those specific tables, the tablet servers hosting more leader replicas for those tables would end up with more resource utilization. 3. With only the patches from KUDU-3497 and KUDU-3390, is table specific leader replica distribution possible, even at the cost of global imbalance of leader replicas? -- To view, visit http://gerrit.cloudera.org:8080/24476 To unsubscribe, visit http://gerrit.cloudera.org:8080/settings Gerrit-Project: kudu Gerrit-Branch: master Gerrit-MessageType: comment Gerrit-Change-Id: I5d44761f6444ca1d1bf4fcee405d65d029e41980 Gerrit-Change-Number: 24476 Gerrit-PatchSet: 1 Gerrit-Owner: Gabriella Lotz <[email protected]> Gerrit-Reviewer: Ashwani Raina <[email protected]> Gerrit-Reviewer: Kudu Jenkins (120) Gerrit-Comment-Date: Wed, 17 Jun 2026 05:05:06 +0000 Gerrit-HasComments: Yes
