Graphileon supports ONgDB
ONgDB is a fork of the neo4j enterprise project that continues development of neo4j enterprise as a fully open source project after Neo4j Inc’s Open Core Shift that suspended development of enterprise as an open source project and removed the open source code.
ONgDB is a high performance, native graph store with everything you would expect from an enterprise-ready database, including high availability clustering, ACID transactions, and uses the intuitive, pattern-centric open cypher query language. Developers use graph theory-based structures that we call nodes and relationships instead of rows and columns. For many use cases, ONgDB will provide orders of magnitude performance benefits compared to non-native graph, relational and NoSQL databases.
