MySQL 5.7 Reference Manual Including MySQL NDB Cluster 7.5 and NDB Cluster 7.6
MySQL applies these rules when various CREATE ... IF
NOT EXISTS statements are replicated:
Every
CREATE
DATABASE IF NOT EXISTS statement is replicated,
whether or not the database already exists on the source.
Similarly, every
CREATE TABLE
IF NOT EXISTS statement without a
SELECT is replicated, whether
or not the table already exists on the source. This includes
CREATE
TABLE IF NOT EXISTS ... LIKE. Replication of
CREATE
TABLE IF NOT EXISTS ... SELECT follows somewhat
different rules; see
Section 16.4.1.6, “Replication of CREATE TABLE ... SELECT Statements”, for
more information.
CREATE EVENT
IF NOT EXISTS is always replicated, whether or not
the event named in the statement already exists on the
source.
