Dgraph vs Titan: What are the differences?
Developers describe Dgraph as "Fast, Distributed Graph DB". Dgraph's goal is to provide Google production level scale and throughput, with low enough latency to be serving real time user queries, over terabytes of structured data. Dgraph supports GraphQL-like query syntax, and responds in JSON and Protocol Buffers over GRPC and HTTP. On the other hand, Titan is detailed as "Distributed Graph Database". Titan is a scalable graph database optimized for storing and querying graphs containing hundreds of billions of vertices and edges distributed across a multi-machine cluster. Titan is a transactional database that can support thousands of concurrent users executing complex graph traversals in real time.
Dgraph and Titan belong to "Graph Databases" category of the tech stack.
Dgraph is an open source tool with 9.95K GitHub stars and 695 GitHub forks. Here's a link to Dgraph's open source repository on GitHub.
