Hongdan Zhu updated HIVE-28655:
-------------------------------
Description:
We need a way to drop the stats associated with the table/partition and its
columns. This can help a lot in migration or replication where the stats data
take huge time to copy. Particularly when the table is partitioned, we have
stats rows for each table, partition, column combination, which can get huge
when the number of partitions is huge.
This is the HMS side changes.
