Neo4j 3.0 is the first release in the 3.x series, featuring a completely redesigned architecture and offering greater scalability, developer productivity, and deployment choices. The new data store expands Neo4j's address space, allowing for graphs of any size. Performance and scale are maintained through dynamic pointer compression and index-free adjacency. The cost-based query optimizer has been improved with added support for write queries and parallel indexes capability. Official language drivers backed by the Bolt binary protocol enable full-stack developers to build powerful applications. Java Stored Procedures provide direct access to the graph, giving developers a way to run imperative code when needed. Neo4j Browser Sync allows users to synchronize saved scripts and graph style sheets across connections. The new release also streamlines operations with a single config file structure and aggregation of log files.
