kiszk commented on issue #27507: [SPARK-24884][SQL] Support regexp function regexp_extract_all URL: https://github.com/apache/spark/pull/27507#issuecomment-585879798 I misunderstood one thing. In this PR, in my understanding, both cache w/ and w/o codegen can achieve the same advantage. Do you have performance numbers w/ and w/o codegen? I think that both can achieve a similar performance while we execute the same SQL multiple times. Am I wrong?
