Events and Event Handling

vFabric GemFire provides versatile and reliable event distribution and handling for your cached data and system member events.

• How Events Work
  Cache events are how your members receive cache updates from other members in your vFabric GemFire distributed system. The other members might be peers to the member, clients or servers, or other distributed systems.
• Implementing GemFire Event Handlers
  You can specify event handlers for region and region entry operations and for administrative events.
• Configuring Peer-to-Peer Event Messaging
  You can receive events from distributed system peers for any region that is not a local region. Local regions receive only local cache events.
• Configuring Client/Server Event Messaging
  You can receive events from your servers for server-side cache events and query result changes.
• Configuring Multi-site Event (WAN) Messaging
  In a multi-site (WAN) installation, event distribution is done for every region in the multi-site-configured system that has enabled gateway communication.
