Ehcache is an open source, standards-based cache for boosting performance, offloading your database, and simplifying scalability. It's the most widely-used Java-based cache because it's robust, proven, and full-featured. Ehcache scales from in-process, with one or more nodes, all the way to mixed in-process/out-of-process configurations with terabyte-sized caches. For applications needing a coherent distributed cache, Ehcache uses the open source Terracotta Sever Array.
Terracotta actively develops, maintains, and supports Ehcache as a professional open source project available under an Apache 2 license. In addition to the full-featured open source Ehcache edition, Terracotta offers enterprise editions of Ehcache with worldwide 24x7 professional support, consulting, and training services.
Ready to create very large in-memory data stores—without worrying about garbage collection performance hits or time-consuming tuning? BigMemory extends Ehcache's' capabilities with an off-heap store that frees you from GC’s constraints. BigMemory uses the Ehcache API for reading and writing, so it's a snap to add to any Ehcache deployment. You also get a search API, advanced in-memory monitoring and management tools, disk-backed, fast restartability, and much more.

Learn more about BigMemory ›Ehcache Search is an addition to the core Ehcache API that lets you query, search and analyze billions of cache entries in memory, with results to complex searches returned in less than a second. By querying the cache directly, you can avoid the time-consuming and expensive process of querying the database, then mapping query results to cache lookups.
