Fast, Transactional, Distributed Graph Database.

Dgraph is an open source, horizontally scalable and distributed graph database, providing ACID transactions, consistent replication and linearizable reads. It's built from ground up to perform for a rich set of queries. Being a native graph 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-like query syntax, and responds in JSON and Protocol Buffers over GRPC and HTTP.

Dgraph is at version 1.0.0 and is production ready.

The quickest way to install Dgraph is to run this command on Linux or Mac.

curl https://get.dgraph.io -sSf | bash

To get started with Dgraph, follow:

• Installation to queries in 3 steps via docs.dgraph.io.
• A longer interactive tutorial via tour.dgraph.io.
• Tutorial and presentation videos on YouTube channel.

• Do you have more than 10 SQL tables, connected to each other via foreign ids?
• Do you have sparse data, which doesn't correctly 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 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.
