> Per table write ID implementation (HIVE-18192) introduces couple of metatables such as NEXT_WRITE_ID and TXN_TO_WRITE_ID to manage write ids allocated per table.
> Now, when we rename any tables, it is necessary to update the corresponding table names in these table as well. Otherwise, ACID table operations won't work properly.
