Questions tagged [neo4j-bolt]

Tag for the newly designed remoting protocol BOLT.

The Neo4j 3.0 Milestone 1 release introduced Bolt, a new network protocol designed for high-performance access to graph databases.

Bolt will consolidate and refine all the ways of doing work with Neo4j, providing more consistent access with a pleasant separation of responsibility.

Bolt is a connection-oriented protocol, using a compact binary encoding over TCP or web sockets for higher throughput and lower latency.

BOLT Java, JavaScript and Python drivers are available today.
