maropu commented on issue #27019: [SPARK-30027][SQL] Support codegen for aggregate filters in HashAggregateExec URL: https://github.com/apache/spark/pull/27019#issuecomment-576100488 @kiszk I added the performance numbers in the PR description. I think the codegen for hash-aggregates can have performance gains in most queries. But, aggregate filters (recently merged in the master) forcibly disable the codegen. So, I think this fix has a good effect on performance.
