16.4.1.9 Replication of DROP ... IF EXISTS Statements
The DROP DATABASE IF EXISTS
, DROP TABLE IF EXISTS
, and DROP VIEW IF EXISTS
statements are always replicated, even if the database, table, or view to be dropped does not exist on the source. This is to ensure that the object to be dropped no longer exists on either the source or the replica, once the replica has caught up with the source.
DROP ... IF EXISTS
statements for stored programs (stored procedures and functions, triggers, and events) are also replicated, even if the stored program to be dropped does not exist on the source.
