What is this?
NebulaGraph is an open-source distributed graph database built to handle large volumes of highly connected data with millisecond latency and quick horizontal scaling.
NebulaGraph is an open-source distributed graph database built to handle large volumes of highly connected data with millisecond latency and quick horizontal scaling.So is it a single-server database, or do I run it as a cluster?It is distributed by design: storage and computing are separate components that scale out horizontally, and the RAFT protocol keeps data strongly consistent across nodes.
