Hi @GaominZ 

"clean base table rotation" refers to the process of automatically managing the size of a database table by periodically creating new, empty "rotation" tables, transferring data from the old table to the new one, and then deleting the old table once the data is migrated, effectively keeping only a certain amount of recent data within the table rotation cycle; this helps maintain performance and prevent the database from becoming too large by automatically removing older data.

Please also refer this: Table Rotation 

If my response helped, please mark it helpful and accept the solution so that it benefits future readers.
