Reliable Event Notification Examples

These examples demonstrate how you can fine-tune the events your clients receive from the server by using event subscriptions.

You can register subscriptions for specific data keys, data keys matching a regular expression, and data matching a continuously running query. The client receives automated notifications from the server whenever the indicated data changes. For key registration, the change is any change to the data object. For continuous queries, the change is any change to the query result set for the query.
