slave_ddl_exec_mode
How replication events should be executed. Legal values are STRICT and IDEMPOTENT (default). In IDEMPOTENT mode, replication will not stop for DDL operations that are idempotent. This means that CREATE TABLE is treated as CREATE TABLE OR REPLACE and DROP TABLE is treated as DROP TABLE IF EXISTS.
