If the target table of the INSERT OVERWRITE is an [AUTO-PARTITION-table](../../../../advanced/partition/auto-partition), then new partitions can be created if PARTITION is not specified (that is, rewrite the whole table). If PARTITION for overwrite is specified(Includes automatic detection and overwriting of partitions through the `partition(*)` syntax), then the AUTO PARTITION table behaves as if it were a normal partitioned table during this process, and data that does not satisfy the existing partition conditions is filtered instead of creating a new partition.
