vincentchenjl opened a new pull request #4984: [TE] Fix over-scheduling tasks in data availability scheduler URL: https://github.com/apache/incubator-pinot/pull/4984 This PR is to fix the issue when detection jobs doesn't move the watermark forward and the data availability keeps scheduling detection tasks for the same detection. To solve it, we add scheduling window logic in which the scheduler only schedule new detection tasks. If the watermark does not move forward for any reason after the detection job runs, the scheduler will try scheduling it a few times and stop due to being out of the scheduling window.
