[GitHub] [pinot] sajjad-moradi opened a new pull request, #8598: Fix bug in rebalance of realtime tables with replica group segment assignment
sajjad-moradi opened a new pull request, #8598:
URL: https://github.com/apache/pinot/pull/8598
## Description
Rebalance of realtime tables with replica group segment assignment is currently done in a partition-by-partition way which leads to an imbalanced assignments. This PR fixes the issue by grouping all partitions belonging to each instancePartition and then reassigning each group of partitions separately.
## Testing Done
Coincidentally the existing number of segments in the unit tests leads to a balanced assignment! Now, that number is changed and the existing test fails without the fix.
