gemfire data distribution among nodes

This is one of the most frequently asked questions. Info below comes from

1) Consistency Model —
* Distribution without ACKs
* Distribution With ACKs
* Distribution With global locking

2) Pub-Sub semantics —

3) Multiple transports —
UDP MultiCast
(See sys admin guide

4) multi-site member discovery/communication


You need to keep your distributed system from splitting into two separate running systems when members lose the ability to see each other, as shown in Network Failure-Network Partition Configurations. When a network failure, or partitioning, occurs, the problem could result in data inconsistencies or a forced disconnect. The solution for this problem is to stop one of the two subgroups from continuing to operate independently.
