xyuanlu opened a new issue #1539: URL: https://github.com/apache/helix/issues/1539
### Describe the bug We found TaskScheduling stage is slow for task intensive workloads. From profiling result, we found the problem is: TaskSchedulingStage.scheduleWorkflows -> getHelixPropertyStore() and CallBackHandler.invoke() all synchronized on zkHelixManager object, witch makes TaskSchedulingStage extremely slow. ---------------------------------------------------------------- This is an automated message from the Apache Git Service.
