Day Software, well known for their Communiqué content management solution, has just released the latest version of their Content Repository with some interesting new enhancements. These enhancements provide enterprise level implementations with more advanced backup and recovery, higher performance and scalability and increased development capabilities.With the ability to manage both structured and unstructured content, Day's latest version of their JSR 170 standard Java Content Repository is CRX 1.4 -- Content Repository Extreme, is a technology that should capture the attention of many enterprises. Enhancements to this latest version include:

Performance and Scalability Enhancements

The use of TarPM -- Tar Persistence Manager -- for performance and scalability improvements. TarPM is a disk-based persistence technology that uses the standard Tar file format and is suitable for high data creation and modification. It has been optimized for use for JCR-based repositories -- in particular it takes advantage of the key-value pair data structure of the CRX and maintains index files for fast access to content.

TarPM provides both vertical and horizontal scalability:* Vertical - supports Data Store technology* Horizontal - supports clustered environments

Availability and Backup/Recovery

Administrators now have the ability to add or restore cluster nodes at run-time and they can perform hot backups at any time thanks to TarPM.

CRX 1.4 comes with a new web development framework based on REST and Apache Sling called the CRX Launchpad. This new framework is supposed to allow developers to use their preferred programming language -- meaning it's not bound to Java.

Apache Jackrabbit

This release of the CRX is based on the latest unmodified official Jackrabbit release and is "code drop-in" compatible. What does this mean?* Easily upgradeto the Day CRX from an Apache Jackrabbit Repository without configuration changes or a content migration* Apply bug fixes to the CRX that were implemented in Apache Jackrabbit and vice versa* Easily migrate to the CRX from Jackrabbit* Support for Source Code Debugging of Apache Jackrabbit components is now included

Don't forget about Day's JCR Cup competition. They extended the entry deadline to September 30th to allow more time for entrants to develop their creations.Whether you are an administrator, developer or manager, you can learn more about Day and their solutions from a set of presentations on their website. These presentations were given at their Business and Technology Summit in May of this year. There's a detailed technical presentation on TarPM.
