/**
* A {@link PinotTaskGenerator} implementation for generating tasks of type
{@link MergeRollupTask}
*
- * TODO: Add the support for realtime table
+ * Assumptions:
+ * - When the MergeRollupTask starts the first time, records older than the
bufferTimeMs have already been ingested.
Review Comment:
Good point!
If I understand correctly, we are using `maxEndTimeMs - bufferTimeMs`. See
the method `getValidBucketEndTimeMsForSegment` for details.
I will update the comment.

Review Comment:
maybe `filter out` is confusing here? Let me change it to `don't process`
