JanusGraph is an open-source, distributed graph database optimized for storing and querying graphs with billions of vertices and edges across a multi-machine cluster. It natively integrates with the Apache TinkerPop stack (Gremlin query language), supports pluggable storage backends like Cassandra, HBase, Bigtable and ScyllaDB, optional full-text search via Elasticsearch/Solr/Lucene, and OLAP analytics through Apache Spark.

Use cases

• store and query a graph with billions of vertices and edges
• run real-time graph traversals for a recommendation engine
• build a fraud detection or knowledge graph backend
• run OLAP graph analytics over a large property graph with Spark
• add full-text and geo search over graph data with Elasticsearch
• self-host a scalable graph database on Cassandra or HBase

When to choose

• you need a massively scalable, transactional graph database that fits the TinkerPop/Gremlin ecosystem
• your graph data exceeds what a single-machine graph database can handle
• you want pluggable storage backends and optional search integration

When to avoid

• your dataset is small enough for an embedded or single-node graph database
• you need a relational or document data model rather than a property graph
• you cannot operate a multi-node cluster with external storage backends
