> From my tests SMJ requires more memory than HJ with a large number of partitions (like 32), so switching from HJ to SMJ makes memory situation worse not better in that case. I think that makes sense when all memory can be in memory, but is that also the case when memory is constrained (e.g. limiting the amount of memory so it _has_ to spill to disk)? I think that's what is proposed here. -- This is an automated message from the Apache Git Service.
