Change subject: IMPALA-13453: Avoid reloading partition if it is unchanged ...................................................................... IMPALA-13453: Avoid reloading partition if it is unchanged In table level REFRESH, we check whether the partition is actually changed and skip updating unchanged partitions in catalog. However, in partition REFRESH, we always drop and add the partition. This leads to unecessarily dropping the partition metadata, column statistics and adding them back again. This patch adds a check to verify if the partition really changed before reloading the partition to avoid unnecessary drop-add sequence.
