The region is the core building block of the Pivotal GemFire distributed system. All cached data is organized into data regions and you do all of your data puts, gets, and querying activities against them.
Pivotal GemFire provides
gfshcommands, APIs, and XML configuration models to support the configuration and management of data regions.
To be able to perform all available operations on your data regions, follow these region naming guidelines.
GemFire provides region shortcut settings, with preset region configurations for the most common region types. For the easiest configuration, start with a shortcut setting and customize as needed. You can also store your own custom configurations in the cache for use by multiple regions.
Use these examples to get started with GemFire region shortcuts.
Use region attributes to fine-tune the region configuration provided by the region shortcut settings.
Use custom attributes to store information related to your region or its entries in your cache. These attributes are only visible to the local application and are not distributed.
A new region or distributed system may need to be loaded with the data of an existing system. There are two approaches to accomplish this task. The approach used depends upon the organization of both the new and the existing distributed system.
