[GitHub] [pinot] liuchang0520 opened a new issue #7415: Fix data racing issue introduced in #6778
liuchang0520 opened a new issue #7415:
URL: https://github.com/apache/pinot/issues/7415
#6778 introduced LLC segments deep store upload retry logic in controller periodic task. There is one potential data racing issue: during the controller periodic job setup, it scans LLC segment ZK metadata to find those without deep store, and let the leader controller to cache them for later fix operation. But by that time, the controller leadership may not be established due to the fact that the controller leadership is determined via Helix asynchronous transition.
One solution is to add controller leadership callback to fix this data racing issue.
