isDiscoverable

public boolean isDiscoverable()

Overrides:

isDiscoverable in class DruidService

Returns:

Whether the service should be discoverable. The default implementation returns true. Some implementations may choose to override this so that the service is not discoverable if it has not been configured. This will not throw a fatal exception, but instead will just skip binding and log a message. This could be useful for optional configuration for the service.
