What's in 1.3?Aside from the license changes, we've added so much cool stuff to Neo4j 1.3 over the course of the last 5 milestone releases. Here's a taste of some of the features that we really love:
Supersize me!Each database can now contain 32 billion nodes/relationships and up to 64 billion properties. That's enough to usefully store Earth's population for a while to come.
Warning: this requires specific action, to upgrade your database from 1.2 to 1.3. See more in the Neo4j manual.
Unsupersize me!The database footprint has been reduced, thanks to an new storage strategy for common short strings (e.g. zip codes). For many data sets, this results in dramatically smaller files on disk and a bonus performance bump.
What you graph is what you see (WYGIWYS)
The completely revamped Webadmin tool looks stunning and is much more usable, with a new integrated visual data browser that lets you jump into and explore a pictorial representation of the graph from any Webadmin screen in just a click!
Developers, developers, developersOur graph database gives developers a natural way to persist complex data. This release includes even more power without compromising ease of use:
- We've added Dijkstra algorithm for finding shortest paths to our library of graph algorithms.
- Our APIs have undergone a spring clean with improvements to the traversal framework and a new, improved look for the indexing API and the underlying implementation (which sadly means old indexes will have to be rebuilt, but it's worth it!).
- RESTafarians will be pleased to know we now support advanced index queries through our REST API, and we've separated out the server plugin API so building server plugins requires a minimal set of dependencies.
Neo4j ProductsAs we’ve mentioned, Neo4j Community is now available under the GPLv3. For other deployments where you have greater needs around management or availability, we're launching two new commercial products: Advanced and Enterprise.
Here's a breakdown of how the product family is structured:
- Community: All the core features of Neo4j embedded and server including the fully ACID transactional graph database engine (available under the GPL or commercial license for OEM)
- Advanced: Everything from the community edition plus management features and additional support services (available under the APGL or a commercial license)
- Enterprise: Everything from the Advanced edition plus High Availability features and even more support services (available under the APGL or a commercial license)
