MariaDB Protocol Module

MariaDB Protocol Module

The mariadbprotocol module implements the MariaDB client-server protocol.

The legacy protocol names mysqlclient, mariadb and mariadbclient are all aliases to mariadbprotocol.

Configuration

Protocol level parameters are defined in the listeners. They must be defined using the scoped parameter syntax where the protocol name is used as the prefix.

[MyListener]
type=listener
service=MyService
protocol=mariadbprotocol
mariadbprotocol.allow_replication=false
port=3306

For the MariaDB protocol module, the prefix is always mariadbprotocol.

allow_replication

  • Type: boolean
  • Mandatory: No
  • Dynamic: Yes
  • Default: true

Whether the use of the replication protocol is allowed through this listener. If disabled with mariadbprotocol.allow_replication=false, all attempts to start replication will be rejected with a ER_FEATURE_DISABLED error (error number 1289).
