This page contains the latest compiled builds of Pentaho Data Integration (Kettle) community edition.  The builds are based on source code downloaded daily from SVN. Why download these snapshot builds? You want the latest version - to get the latest features in PDI. You want a more stable version - PDI point releases (e.g. 4.0.1) can include important bug fixes - see the PDI JIRA system for a full list of known issues. You need a bug fixed - You're struggling with a critical bug which has been fixed in a more recent version. To save time - You haven't got the time and/or inclination to learn about how to download PDI from SVN and build your own version.

Caching is the most important performance optimization technique. There are many things that can be cached in persistence, objects, data, database connections, database statements, query results, meta-data, relationships, to name a few. Caching in object persistence normally refers to the caching of objects or their data. Caching also influences object identity, that is that if you read an object, then read the same object again you should get the identical object back (same reference). JPA 1.0 does not define a shared object cache, JPA providers can support a shared object cache or not, however most do. Caching in JPA is required with-in a transaction or within an extended persistence context to preserve object identity, but JPA does not require that caching be supported across transactions or persistence contexts. JPA 2.0 defines the concept of a shared cache. The @Cacheable annotation or cacheable XML attribute can be used to enable or disable caching on a class.

The Java Content Repository (JCR) standard, which is based on the Java Specification Requests JSR170 (version 1.0) and JSR 283 (version 2.0), provides a Java-centric object-oriented storage API specifically targeted at content management scenarios. The JCR is not a content management system or a full-fledged content management system API, but rather a content repository API. A content repository provides a common API for all content-driven applications and CMS components, which require access to the content. It provides methods to read, write, and query content. The primary motivation of the JCR standard is to provide a standard and vendor-neutral programmatic interface for content repositories, allowing applications of multiple vendors to interact efficiently.

"XMPP Web Services for Java (xws4j) is an implementation of machine to machine communication over XMPP according to the XMPP Extension Protocol XEP-0244 - IO Data and others.

""Coming from desktop application development, I have found the IT Mill Toolkit [Vaadin] to be a lot of help in the transition to web application development. With the toolkit, writing AJAX enabled web applications is as easy as writing Swing based GUI code. It hides so many frustrating details, and handles browser independence so I don't have to worry about it. Using the toolkit makes it quite easy for me to write sophisticated web applications."
