Region Endpoints

This topic provides links to information about VMware GemFire regions. GemFire logically groups data within its cache in GemFire Regions. Regions stores data as entries, which are key-value pairs. Using the REST APIs you can read, add, update, and delete region data.

For more in information about working with regions, see Data Regions.
