DeepaMehta 4.0.14 released

Main focus of DeepaMehta 4.0.14 is better Performance, in particular when there is a lot of content in the database. All the changes are behind the scenes. The user will perceive nothing but performance. The original problem background is described in a mailing list posting.

The storage layer of DeepaMehta 4.0.14 is completely rewritten. It features High-speed traversal: a Lucene index for associations significantly speeds up traversal. In particular, highly connected nodes ("supernodes") have no negative impact on traversal speed anymore. Compact architecture: the storage implementation is coded directly to the DeepaMehta Model API. The additional MehtaGraph bridging layer is dropped. Modular storage layer: 3rd-party developers are enabled to implement alternate DeepaMehta storage layers, based on arbitrary databases. A Storage layer implementation is deployed as an OSGi service.

For more changes and details see the Release Notes.
