Multi-site (WAN) Configuration
Use the multi-site configuration to scale horizontally between disparate, loosely-coupled clusters. A wide-area network (WAN) is the main use case for the multi-site topology.
The VMware GemFire® multi-site implementation connects disparate clusters. The systems act as one when they are coupled, and they act as independent systems when communication between sites fails. The coupling is tolerant of weak or slow links between cluster sites. A wide-area network (WAN) is the main use case for the multi-site topology.
To configure your multi-site topology, you should understand the recommended topologies and the topologies to avoid.
Plan and configure your multi-site topology, and configure the regions that will be shared between systems.
You can optionally create gateway sender and/or gateway receiver filters to control which events are queued and distributed to a remote site, or to modify the data stream that is transmitted between VMware GemFire sites.
You can optionally create a
GatewayConflictResolvercache plug-in to decide whether a potentially conflicting event that was delivered from another site should be applied to the local cache.
