What's new in Neo4j 2.2.0M04 Milestone:

  • Highly Concurrent Performance:
  • With Neo4j 2.2, we introduce a brand new page cache designed to deliver extreme performance and scalability under highly concurrent workloads. This new page cache helps overcome the limitations imposed by the current IO systems to support larger applications with hundreds of read and/or write IO requirements. The new cache is auto-configured and matches the available memory without the need to tune memory mapped IO settings anymore.
  • Transactional & Batch Write Performance:

Neo4j is an embedded, disk-based, fully transactional Java persistence engine that stores data structured in graphs rather than in tables.

A graph (mathematical lingo for a network) is a flexible data structure that allows a more agile and rapid style of development.

You can think of Neo4j as a high-performance graph engine with all the features of a mature and robust database. The programmer works with an object-oriented, flexible network structure rather than with strict and static tables — yet enjoys all the benefits of a fully transactional, enterprise-strength database.

In addition, Neo4j includes the usual database features: ACID transactions, concurrency control, transaction recovery, durable persistence, and everything else you would expect from an enterprise-strength database.
