### `replication_user`
The username of the replication user. This is given as the value for
`MASTER_USER` whenever a `CHANGE_MASTER_TO` command is executed.
Both `replication_user` and `replication_password` parameters must be defined if
a custom replication user is used. If neither of the parameters is defined, the
`CHANGE MASTER TO` command will use the monitor credentials for the replication

### `replication_password`
The password of the replication user. This is given as the value for
`MASTER_USER` whenever a `CHANGE_MASTER_TO` command is executed.
See `replication_user` parameter documentation for details about the use of this
parameter.
