What is a Geode cache?

Geode is a distributed in-memory data grid supporting caching and data computation. It provides different APIs and XML configuration models to support the behaviors of different members. The cache provides in-memory storage and management for your data. You organize your data in the cache into data regions, each with its own configurable behavior. You store your data into your regions in key/value pairs called data entries. The cache also provides features like transactions, data querying, disk storage management, and logging.
