Direct Known Subclasses:

PeeredDatabaseConfigRegistry

public class DatabaseConfigRegistry
extends ConfigRegistry

Implements the ConfigRegistry using a JDBC database as a persistent store for the configuration information. Note: config objects should only be created during server startup because they will result in synchronous requests to load up the initial configuration data from the database. This ensures that systems initialized after the config registry can safely make use of configuration information.

Creates a configuration registry and prepares it for operation.

Parameters:

ctx - will provide access to our database.
