Titan has been decommisioned after the takeover by Datastax. It will be removed from the DB-Engines ranking. A fork has been open-sourced as JanusGraph.
DescriptionAn embedded key-value store for Go.All data is stored inside objects which are linked by so-called link attributes. Objects consist of classes which can be extended and de-extended at runtime. Graphs can be defined with a struct.A Graph DBMS optimized for distributed clusters infoIt was forked from the latest code base of Titan in January 2017Oracles in-memory data grid solutionTitan is a Graph DBMS optimized for distributed clusters.
