JanusGraph is a scalable graph database optimized for storing and querying graphs containing hundreds of billions of vertices and edges distributed across a multi-machine cluster. JanusGraph is a transactional database that can support thousands of concurrent users executing complex graph traversals in real time.
In addition, JanusGraph provides the following features:
- Elastic and linear scalability for a growing data and user base.
- Data distribution and replication for performance and fault tolerance.
- Multi-datacenter high availability and hot backups.
- Support for ACID and eventual consistency.
- Support for various storage backends:
- Support for global graph data analytics, reporting, and ETL through integration with big data platforms:
- Support for geo, numeric range, and full-text search via:
- Native integration with the Apache TinkerPop™ graph stack:
- Open source under the Apache 2 license.
- You can visualize graphs stored in JanusGraph via any of the following tools:
- Cytoscape
