Neo4J is cloud bound as Version 1.6 is now GA

The latest version of highly-acclaimed Java-implementable NoSQL graph database Neo4J has been released, with an extra bonus for users – a public beta for a Heroku based cloud solution that could take things to the next level.

A lot of work has been done with the query language Cypher within Neo4j, although from a glance it may not be noticable with much being done internally. The type system has been rebuilt and revamped, and a second simpler, pattern matcher has been added, which should make the code base and queries run that much quicker. Granvik explained more of the Cyper changes:

User facing changes include: possibility to get all shortest paths, the COALESCE function, column aliasing, and the possibility for variable length relationships to introduce an iterable of the relationships.

More, array properties have been supported in Neo4j for a long time, but until now it wasn’t possible to query on them. This release makes it possible to filter on array properties in Cypher. We have also improved aggregation performance.

Finally, there are two breaking changes – the syntax for the ALL/NONE/ANY/SINGLE predicates has changed, and the ExecutionResult is now a read-once, forward only iterable.

Other enhancements within this release include an improved web admin interface, including fully integrated Shell Neo4j commands, kernel changes and an upgrade to Lucene 3.5. The team are eager to hear feedback from the community and will make notes of improvements suggested for later releases. Download now!
