Questions tagged [ehcache]

Ehcache is an open source, standards compliant Java-based cache used to boost performance, offload the database and simplify scalability.

Ehcache is robust, proven and full-featured, which has made it the most popular Java-based cache with 100,000’s of production deployments.

It can scale from an in-process cache on one or more nodes through to a mixed in-process/out-of-process configuration capable of terabyte-sized caches. The open source Terracotta Server Array snaps in to provide a coherent distributed cache.

Ehcache is actively developed, maintained and supported as a professional open source project by Terracotta, Inc. and is available under an Apache 2 license.

For more information, see the EHCache website.
