Terracotta software products and projects are made available in several packaged kits. In addition to releasing individual products/projects as kits (such as Ehcache and Quartz Scheduler), the Terracotta kit is a package that includes the Terracotta platform, Ehcache, Quartz Scheduler, Sessions, and related items. 

The following table provides the most current information on these releases.

Understanding Terracotta Kit Names and Version Numbers

Kit names include the kit content (whether it is an individual product/project - such as Ehcache - or a full Terracotta kit), a version, and possibly some additional attributes.

Terracotta kits have a version number that in general refers to the platform version.

A kit version number can also have one of the following attributes to indicate its purpose or a change other than to the platform:

• _ (Underscore) – A kit containing the same platform as the non-underscore version but at least one major Terracotta component with a version change. Major components are Ehcache, Quartz Scheduler, Sessions, and the Toolkit. For example Terracotta 3.4.0_1 is identical to Terracotta 3.4.0 except that Ehcache 2.3.0 was replaced with Ehcache 2.3.1.
• ee – Included in the name indicates that this is an Enterprise Edition product release (a commercial version that requires a license to run) as opposed to an Open Source project release.
• Beta – A pre-release kit intended for beta testing.
• RC (Release Candidate) – A kit that is a candidate to become the final release unless issues are discovered that must be fixed before a final release is made. A release candidate is suitable for late-stage testing.
• SNAPSHOT – Snapshots reflect the code as it currently exists, and are not official releases. Snapshot kits can change daily and may have functional and performance issues. For example, Terracotta 3.5.0-SNAPSHOT may be suitable for early testing purposes, but is not recommended for POCs.
• patch – A patch to an ee (Enterprise Edition) kit. See below for more details.

Software Patches

Patches are a provided for ee (Enterprise Edition) kits for commercial customers only. For more information on using software patches, see Patches.

Terracotta 10.x is a distributed in-memory data management solution for both operational and analytical workloads.  Terracotta DB has powerful query and computation capabilities, leveraging native JDK features such as Java Streams, collections, and functions. 

Current Releases

Terracotta Ehcache is a standards-based cache that boosts performance, offloads your database, and simplifies scalability. It's the most widely-used Java-based caching platform in the world for its ability to integrate with other popular libraries and frameworks like Hibernate, Spring, etc. Terracotta Ehcache scales from in-process caching, all the way to mixed in-process/out-of-process deployments with terabyte-sized caches. It strengthens distributed caching capabilities via a new generation of Terracotta server with support for high-availability and improved performance.

Some key features include:

• An API that leverages Java generics and simplifies Cache interactions
• Java-based Key/Value store optimized for caching workloads
• Full compatibility with javax.cache API (JSR-107)
• The industry's first and best Offheap storage capabilities, including offheap-only caches
• In-memory storage with optional persistence to disk and ultra-fast recovery
• Out of the box Spring Caching and Hibernate integration thanks to the javax.cache support, and many more ...
• Distributed caching:
  • Supports various scale-out and HA deployment configurations
  • Flexible, fine-granular configuration of availability, consistency, and durability

Ehcache also is alive as an open source project. Outside of this distribution, Ehcache builds are available on the project's GitHub release page at https://github.com/ehcache/ehcache3/releases.

Terracotta Ehcache is simply a sub-set of the Terracotta 10.x product, providing a means for commercial licensing and support of only the caching API/capabilities of Terracotta.  Therefore, see the Terracotta 10.x release notes for relevant information about Terracotta Ehcache releases.
