Reconfigures a MySQL DB instance to no longer be a Read Replica of an instance of MySQL running external to Amazon RDS.
mysql.rds_reset_external_master procedure must be run by the
master user. It must be run on the MySQL DB instance to be removed as a Read Replica
of a MySQL instance running external to Amazon RDS.
We recommend that you use Read Replicas to manage replication between two Amazon RDS DB instances when possible, and only use this and other replication-related stored procedures to enable more complex replication topologies between Amazon RDS DB instances. These stored procedures are primarily offered to enable replication with MySQL instances running external to Amazon RDS. For information about managing replication between Amazon RDS DB instances, see Working with PostgreSQL, MySQL, and MariaDB Read Replicas.
For more information about using replication to import data from an instance of MySQL running external to Amazon RDS, see Importing and Exporting Data From a MySQL DB Instance.
mysql.rds_reset_external_master procedure is available in these versions
of Amazon RDS MySQL:
MySQL 5.5 version 5.5.33 and later
