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 solutionScalable, distributed, serverless MySQL database platform built on top of Vitess
