What is JanusGraph?

JanusGraph is a distributed, open-source graph database. It is designed to support very large graphs (billions of vertices and edges) and high transaction volumes. JanusGraph is highly scalable and fault-tolerant, and it supports various storage backends (like Cassandra, HBase, and Bigtable) and indexing backends (like Elasticsearch, Solr, and Lucene). It is commonly used for applications such as knowledge graphs, recommendation engines, fraud detection, and network analysis where relationships between data points are critical.
