Detailed Description

Implementers of interface

PartitionResolver enable custom partitioning on the PartitionedRegion.

The Key class or callback arg can implement PartitionResolver interface to enable custom partitioning OR
Configure your own PartitionResolver class in partition attributes (For instance when the Key is a primitive type or String) Implement the appropriate equals - For all implementations, you need to be sure to code the class equals method so it properly verifies equality for the PartitionResolver implementation. This might mean verifying that class names are the same or that the returned routing objects are the same etc.. When you initiate the partitioned region on multiple nodes, GemFire uses the equals method to ensure you are using the same PartitionResolver implementation for all of the nodes for the region. GemFire uses the routing object's hashCode to determine where the data is being managed.
