Thanks for the analysis @ic4y ! I am quite surprised we pay the fragmentation that comes from the row oriented structure of `Accumulators` that much more at de-allocation time than when computing the actual aggregates. I guess the arena strategy that you are suggesting should work, though I don't know bumpalo specifically. It is worth referencing your discussion about making accumulators column based in #956, which I believe should also solve this issue. -- This is an automated message from the Apache Git Service.
