You create cache regions either programmatically or through declarative statements in the cache.xml file. Generally, a cache is organized and populated through a combination of the two approaches.

A distributed region can be either non-partitioned or a partitioned region. See the GemFire User's Guide for detailed descriptions of both non-partitioned and partitioned regions. Region creation is subject to attribute consistency checks. The requirements for consistency between attributes are detailed both in the online API documentation and throughout the discussion of Region Attributes.

See the GemFire User's Guide for a complete description of consistency checking in Pivotal GemFire.
