DGraph: Native GraphQL Database with Graph Backend

The Only Native GraphQL Database With A Graph Backend.

Dgraph is a horizontally scalable and distributed GraphQL database with a graph backend. It provides ACID transactions, consistent replication, and linearizable reads. It's built from the ground up to perform for a rich set of queries. Being a native GraphQL database, it tightly controls how the data is arranged on disk to optimize for query performance and throughput, reducing disk seeks and network calls in a cluster.

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 query syntax, and responds in JSON and Protocol Buffers over GRPC and HTTP.

Get Started

To get started with Dgraph, follow:

Is Dgraph the right choice for me?

  • Do you have more than 10 SQL tables connected via foreign keys?
  • Do you have sparse data, which doesn't elegantly fit into SQL tables?
  • Do you want a simple and flexible schema, which is readable and maintainable over time?
  • Do you care about speed and performance at scale?

If the answers to the above are YES, then Dgraph would be a great fit for your application. Dgraph provides NoSQL like scalability while providing SQL like transactions and the ability to select, filter, and aggregate data points. It combines that with distributed joins, traversals, and graph operations, which makes it easy to build applications with it.
