@alamb Thank you for the review! I have significantly reworked this PR in a new PR #7655, relying primarily on column wise parallelization rather than row group wise. The new approach is much more complex in the code, but the performance advantage is huge. 20% faster and 90% lower memory overhead vs. this PR. -- This is an automated message from the Apache Git Service.
