Release Notes for Fremantle Beta 1

Overview

Fremantle is the project name for the next major release of Ehcache, Quartz and the Terracotta platform, namely:

  • Ehcache 2.4.0
  • Quartz 2.0.0
  • Terracotta 3.5.0

Summary of Changes

Ehcache

  • Addition of Ehcache Search (see below)
  • Improvements to Enterprise Ehcache Disk Store (for use in conjunction with BigMemory)
  • New local and local_jta Ehcache transaction modes
  • NonStopCache is now in core
  • Explicit locking is now in core
  • Updated Extjs toolkit in Ehcache Monitor
  • Usability improvements to Ehcache Monitor

Quartz

  • New fluent configuration API (see below)
  • Quartz Where - permitting control of where jobs execute in a clustered environment through node groups and node type constraints

Terracotta

  • Server-side (L2) BigMemory enhancement (eg better defaults, removal of chunk/segment size restrictions, auto-tuning of chunk and segment sizes, better protection from OOMEs, ...)

About Ehcache Search

The Ehcache Search API allows you to execute arbitrarily complex queries against Ehcache. The standalone Ehcache Search implementation is limited to the memoryStore (ie it has no support for diskStore or BigMemory - aka offHeapStore). Ehcache Search support for distributed caches is an Enterprise-only feature, and is designed to work across all Terracotta server storage tiers (memory, BigMemory, and disk).

The easiest way to get started with the API is to try the sample application posted on github. This includes a ready to run bundle for *nix (just download, unpack, and execute with 'sh run.sh'). This bundle also includes a maven pom to rebuild (using the latest SNAPSHOT rather than that in the bundle): https://github.com/sharrissf/Ehcache-Search-Sample/downloads

Ehcache Search docs are here: http://ehcache.org/documentation/search.html

About Quartz 2.0

Please see the What's new in Quartz 2.0 document here ....Add link to James' 2.0 Doc

Note: Quartz Where is only supported when using the TerracottaJobStore, and is an enterprise-only feature.
