+Mark the tables as deleting,



DESCRIPTION:

When DROP DATABASE executed keycache of tables of the database flushed to disk
before removing table which is wasting of resources. So better to have table
removed from keycache without writing changes on disk as it was done for DROP TABLE.


HIGH-LEVEL SPECIFICATION:



Mark the tables as deleting,


LOW-LEVEL DESIGN:



mark tables of the database as deleting when we remove them from table cache
(before removing from keycache).
