performance regression is what we need concern about. @wecharyu has did some benchmark to validate the performance is ok after this change. But the benchmark is on the local HMS benchmark tools, maybe this can not show the actual production use case? It's better to do a more extreme benchmart test, as HIVE-11786 said, `2million+ in PART_COL_STATS`. @wecharyu Do you have any actual production use case(big partitions with PART_COL_STATS) to show no performance regression for this change? -- This is an automated message from the Apache Git Service.
