[GitHub] [arrow] js8544 commented on pull request #14535: ARROW-18185: [C++][Compute] Support KEEP_NULL option for compute::Filter

js8544 commented on PR #14535:
URL: https://github.com/apache/arrow/pull/14535#issuecomment-1294421635

   Benchmark result on my machine: https://gist.github.com/js8544/7a1a1e798e41b42f51ccb4112bd2a2c2
   Benchmark name ending with 2 is with filtered_value_behavior = KEEP_NULL, it is faster than the other two options in most cases, except for the cases when selection percentage is extremely small so it's cheaper to copy over the selected values.
