DescriptionWide-column store based on ideas of BigTable and DynamoDB infoOptimized for write accessA native JSON - document store inspired by Lotus Notes, scalable from globally distributed server-clusters down to mobile phones.Enterprise-ready RDF and graph database with efficient reasoning, cluster and external index synchronization support. It supports also SQL JDBC access to Knowledge Graph and GraphQL over SPARQL.A Graph DBMS optimized for distributed clusters infoIt was forked from the latest code base of Titan in January 2017TypeDB is a strongly-typed database with a rich and logical type system and TypeQL as its query language
