[GitHub] [pinot] Jackie-Jiang opened a new pull request, #10031: Optimize TableRebalancer to not always recompute target assignment when IS changes
Jackie-Jiang opened a new pull request, #10031:
URL: https://github.com/apache/pinot/pull/10031
This is on top of the enhancement in #10028 which fixes the EV converge issue.
Currently in no downtime mode, re-computing the target assignment for large tables could also take a long time. If the computation takes longer than the IS change frequency, it can never catch up and rebalance will run into infinite loop. This PR enhances the logic to use the old target assignment to create the new target assignment when all segments to be moved remain the same in the new IS.
