Hello, do pinot supports upsert for offline tables? or do it only supports that for realtime tables? for example; when late data arrived after the real-time segment is flushed, can pinot update it?

@Oguzhan Mangir At the moment the support is for real-time only. However, Pinot segments don’t need to be time partitioned, so late arriving data is not an issue cc: @Yupeng Fu

Yes, upset is for realtime only, for offline table you can do the compaction in the segment creation job.
