> Is TPC-DS performance no longer regression after the fix? @reswqa The regression still exists because we replace the HashBufferAccumulator with the SortBufferAccumulator when the decoupling is enabled and the parallelism is less than 512, but this PR reduces the regression. According to the previous discussion, the regression is acceptable if the feature is enabled. -- This is an automated message from the Apache Git Service.
