To change the MASTER_HEARTBEAT_PERIOD on an Aurora MySQL version 2 (with MySQL 5.7 compatibility) RDS database, you can use the ALTER USER statement in MySQL. This statement allows you to modify the user accounts that are associated with the Aurora MySQL database, including the MASTER_HEARTBEAT_PERIOD setting.
Here is an example of how you can use the ALTER USER statement to change the MASTER_HEARTBEAT_PERIOD on an Aurora MySQL version 2 RDS database:
ALTER USER 'username'@'hostname' IDENTIFIED BY 'new_password'
REPLICA CHANNEL 'channel_name'
MASTER_HEARTBEAT_PERIOD = 30;
In the example above, you would need to replace 'username' with the actual username of the user account you want to modify, 'hostname' with the hostname of the user account, and 'new_password' with the new password for the user account. You would also need to specify the name of the replication channel (i.e., the channel through which the Aurora MySQL instance replicates data from the source instance) using the 'channel_name' parameter, and specify the new value for the MASTER_HEARTBEAT_PERIOD using the MASTER_HEARTBEAT_PERIOD = 30; clause.
Note that you must have the SUPER privilege to use the ALTER USER statement in MySQL. If you do not have this privilege, you can try using the SET PERSIST statement to change the MASTER_HEARTBEAT_PERIOD instead.
SET PERSIST rds_replication_channel_name.master_heartbeat_period = 30;
In this example, you would need to replace 'rds_replication_channel_name' with the actual name of the replication channel, and specify the new value for the MASTER_HEARTBEAT_PERIOD using the master_heartbeat_period = 30; clause.
I hope this helps! Let me know if you have any other questions.
