Ehcache – standards-based cache that boosts performance

Ehcache is a fast and simple, thread safe, standards based pure Java, in-process cache, which acts as a pluggable cache for Hibernate 2.1.

It has a small memory footprint, minimal dependencies, and comprehensive documentation.

Ehcache is widely used in such open source projects as Hibernate and Spring. Terracotta also offers an enterprise edition.

Features include:

• Scalable:
  • Provides Memory and Disk stores for scalability into gigabytes.
