> Currently the HMS is lack of versioning, the RDMS nowadays provides MVCC for writes not block any reads, so the write is the main concern here. The lock provides here is the row-level lock, it only blocks the write operation against the same table, such as the alter/drop the same table/partition, drop the db, or update the stats of this table/partition.
