Dgraph

Dgraph is a high-performance, distributed graph database built for production-level GraphQL and low-latency applications.

Dgraph delivers a native GraphQL experience by executing queries directly on the database engine. Built in Go, it scales horizontally across commodity hardware to handle petabytes of data while maintaining sub-second response times. The system uses a unique DQL (Dgraph Query Language) for complex joins and provides ACID transactions out of the box. Teams like Intuit and Zeotap use Dgraph to eliminate the overhead of mapping relational tables to graph structures, simplifying their backend stacks into a single, unified data layer.
