Customizing the implementation

The storage component responds to any suitably formatted messages that are published to the configured topic names for each mapped table. You can provide you own implementation of the stored procedures or the notification component.

To publish a change message, the Message Service 'text' property should be “insert”, “delete” or “update”, each key column should have a corresponding property (unless multiple rows were affected in which case key columns should be omitted). If using the Java Message Service (JMS) to publish the messages, use a TextMessage and use header properties for the key column values.
