Coherence™ API Specification.

Coherence™ is a JCache-compliant in-memory caching and data management solution for clustered Java applications.

Coherence™ makes sharing and managing data in a cluster as simple as on a single JVM using Java Collection classes. It accomplishes this by coordinating updates to the data using cluster-wide concurrency control, distributing or replicating data modifications across the cluster using the highest performing clustered protocol available, and delivering notifications of data modifications to any cluster nodes that request them. Developers can easily take advantage of Coherence features using the standard Java Collection API to access and modify data, and the standard JavaBean event model to receive data change notifications.

To get started with Coherence™, please see the JavaDoc for CacheFactory.
