Cayenne

News created by Ari Maniatis on May 29, 2008 09:07 Cayenne 3 is advancing quickly. This latest milestone also fixes a range of ... [More] bugs and is recommended for all users of previous Cayenne 3 milestones. As before, Cayenne 2.x should still be used in preference if you want a stable API with a proven track record. Some of the exciting changes in this milestone of Cayenne include support for outer joins and split expressions, better performance in ROP by sometimes hugely reducing network traffic (CAY-971) and by having the server return lifecycle objects changes to the client automatically, improvements to the modeler, and improving the ability of a paginated list to support many hundreds of thousands of records with efficient use of memory. Of course there is much more besides, so please browse the Jira issues below which interest you. There are very few changes to generics this time, so it should be fairly simple to drop the new jar into your application. Release Download Link All feedback, bug reports or feature requests are welcome and there is still time for new features to be added before 3.0 final release. We encourage you to test it in your application and report back any issues you might have so they can be addressed.

News created by Ari Maniatis on Feb 04, 2008 04:15 The Cayenne team is pleased to present the third milestone of Cayenne 3. ... [More] This is a development branch of Cayenne and still undergoing significant changes. A number of developers are using it in production systems, however if you want the most stable and tested version of Cayenne you should use version 1.x or 2.x which have a proven track record and are widely used in deployment. Release Download Link This milestone release adds some exciting new features, including enhancements to the Cayenne modeler for lifecycle listeners and callbacks and the ability to merge changes to the model back to the database, extensive new work toward full JPA compliance, updates to cgen and the templates, and much more. This release requires Java 5 as a minimum. The decision to change the required JDK was made after a poll of users revealed no substantial need for Java 1.4 and plenty of benefits in moving forward. Generics are only partially completed in the public API at this time and we continue to try and balance the opportunities and headaches of a clean generics interface. All feedback, bug reports or feature requests are welcome and there is still time for new features to be added before 3.0 final release. We encourage you to test it in your application and report back any issues you might have so they can be addressed.

News updated by Andrus Adamchik to revision 2 on Jul 28, 2007 04:55. created by Andrus Adamchik on Jul 28, 2007 03:28 ... [More] Apache Cayenne team is glad to announce the first milestone release of Cayenne 3.0. Download Link The milestone status means that the release is under active development, and some of the new features do not yet have all expected bells and whistles, still the existing core is stable and has been deployed in production by a number of users already. If you look at the list of new features, it has quite a few things. I'll just mention of a few of them here: The most visible addition to Cayenne is a JSR-220 Java Persistence API Provider (aka JPA). I.e. along with familiar Cayenne Persistence API, Cayenne stack now also supports JPA. Current state of the provider can be characterized as "preview" - it is fairly usable but is far from complete. Existing Cayenne Persistence API evolves towards making 'org.apache.cayenne.ObjectContext' interface the main way to access persistence features (vs. using its more familiar concrete implementation - DataContext). The users are encouraged to store context references as ObjectContext whenever possible for maximum flexibility (and portability to the future releases). Another important feature is pluggable query cache that allows fine-tuning of cache size and expiration behavior. From author's experience, this is a life-saver on high-traffic sites, where configurable cache is the key to the good performance. JPA work mentioned above resulted in a number of significant improvements in the existing API. We've added lifecycle callbacks, a powerful new type of object queries - EJBQL Queries, experimental support for POJO persistence. Other nice things like vertical inheritance, embeddables, etc. are coming in the following milestones. Finally, there is a number of performance improvements, such as faster paginated queries, an leak-free DataContext. Here a full list of issue from the release notes (note that bug fixes are tracked since release 2.0, and some of them may already be available in 2.0.3) New Features / Improvements Removed all API deprecated as of 1.2 and 2.0.
