Really nice observation! I think we should drive this further. Some further observations I saw when looking at the current implementation on master for the in memory merging part: * the in memory batches are not cleared after batches are sorted * it is needlessly using `spawn_buffered` in the code for streaming merge () sorting can be done on the spot here and batches dropped as soon as possible. -- This is an automated message from the Apache Git Service.
