Unused CarbonData tables can be deleted. After a CarbonData table is deleted, its metadata and loaded data are deleted together.
DROP TABLE [IF EXISTS] [db_name.]table_name;
db_name is optional. If db_name is not specified, the table named table_name in the current database is deleted.
For example, run the following command to delete the productSalesTable table in the productdb database:
DROP TABLE productdb.productSalesTable;
