Data Definition Language (DDL) statements (operations) are used to define MySQL database structures or schema. You can use these DDL statements for data replication between MySQL source and target databases. MySQL DDL specifics are found in the MySQL documentation at https://dev.mysql.com/doc/.

Oracle GoldenGate 21c for MySQL has introduced a transaction log based replication solution for MySQL 8.0, which has improved performance and usability when compared to the plug-in based DDL replication approach. However, plug-in based DDL replication approach is supported in older releases.
