From what I remember -- doesn't SMJ already fetches buffered side until it meets the first key which is non-equal to the current streamed side value (`PollingRest` buffered state)? It seems to be a solution for waiting the last batch for the key -- for any type (normal/semi/anti) of join, on start of streamed row processing, all required rows from the buffered side should be already read and stored in memory. Or maybe I've mistunderstood the problem? -- This is an automated message from the Apache Git Service.
