Managed Connection

Startup connection and monitoring server change, but you have to startup after setting properties, otherwise, it is of no efficiency.

Startup

dataSource.startup();

Shutdown

dataSource.shutdown();

If this library running with Spring Framework and managed by application context, you don't have to manual startup or shutdown the connection.

Monitoring Topology

You can get server topology status by Connection.

// Get connection by file source.
Connection conn = dataSource.getConnection();
// Get topology status.
conn.getSystemTopologyStatus();
// Get master cluster status.
conn.getSystemClusterStatus();
