Introduction to Ehcache
High-Level Overview
Terracotta Ehcache is a standards-based cache that boosts performance, offloads your database, and simplifies scalability. It's the most widely-used Java-based cache because it's robust, proven, full-featured, and integrates with other popular libraries and frameworks. Terracotta Ehcache scales from in-process caching, all the way to mixed in-process/out-of-process deployments with terabyte-sized caches.
Terracotta Ehcache strengthens the distributed caching capabilities via a new generation of Terracotta server with support for high-availability and improved performance.
Features include:
An API that leverages Java generics and simplifies Cache interactions,
Full compatibility with javax.cache API (JSR-107),
Offheap storage capabilities, including offheap-only caches,
Out of the box Spring Caching and Hibernate integration thanks to the javax.cache support,
And many more ...
Ehcache also is alive as an open source project. Builds are available on the project's GitHub release page at
https://github.com/ehcache/ehcache3/releases.
