Review comment: That would depend on the impl. For say an OFFLINE table, we'd use something like a FileBasedBuffer, and we'll only get the rows into Pinot for querying after a flush is called. But for a realtime table, we'd use a MutableSegmentBuffer, in which case as soon as it's collected, we'll be able to query it ---------------------------------------------------------------- This is an automated message from the Apache Git Service.
