Pivotal GemFire provides versatile and
reliable event distribution and handling for your cached data and system member events.
How Events Work
Members in your Pivotal GemFire distributed system receive cache updates from other members through cache events. The other members can be peers to the member, clients or servers, or other distributed systems.
Configuring Event Queues
In a multi-site (WAN) installation, GemFire uses gateway sender queues to distribute events for regions that are configured with a gateway sender. AsyncEventListeners also use an asynchronous event queue to distribute events for configured regions. This section describes additional options for configuring the event queues that are used by gateway senders or AsyncEventListener implementations.
