> Are there any before/after benchmarks? It's really nice that we can have extra numerical stability, I'm just curious what's the penalty for it. This change is only for combing variances from multiple arrays. The time is trivial compared with computing variance for each array. Benchmark also shows no difference (benchmark PR is pending review, https://github.com/apache/arrow/pull/8407) ---------------------------------------------------------------- This is an automated message from the Apache Git Service.
