What is Ehcache?
Ehcache is an open-source, standards-based cache for boosting performance, offloading your database, and simplifying scalability. As a robust, proven, and full-featured solution, it is today’s most widely used Java-based cache. You can use Ehcache as a general-purpose cache or a second-level cache for Hibernate. You can additionally integrate it with third-party products such as ColdFusion, Google App Engine, and Spring.
Ehcache provides in-process cache, which you can replicate across multiple nodes. It is also at the core of BigMemory Go and BigMemory Max, Terracotta’s commercial caching and in-memory data-storage products. The Terracotta Server Array provided with BigMemory Max enables mixed in-process/out-of-process configurations with terabyte-size caches.
