Dgraph is the ultimate graph database for the modern, GraphQL-first developer. Built from the ground up in Go, it is designed to handle high-performance, real-time queries while maintaining the horizontal scalability expected of modern distributed systems. Unlike legacy graph databases that struggle as they grow, Dgraph's symmetrical architecture allows it to scale out effortlessly across multiple nodes in a cluster.
What sets Dgraph apart is its native support for GraphQL. You don't need a separate API layer or complex mapping logic—simply define your schema and start querying your graph data instantly over HTTP. Its specialized DQL query language provides even deeper power for graph-specific operations like shortest paths and complex relationship traversals.
Self-hosting Dgraph provides organizations with an elite, production-grade graph layer that is both developer-friendly and operationally resilient, perfect for building the next generation of intelligent, data-driven applications.
Key Benefits
- GraphQL Native: Build faster with a database that speaks your application's language.
- Extreme Latency: Optimized for sub-second queries across billions of nodes and edges.
- Easy Scaling: Simply add more Alpha nodes to increase storage and query throughput.
- Data Integrity: Fully ACID compliant transactions even in a distributed environment.
- All-in-One Search: Integrated search capabilities mean you don't need a separate Elasticsearch instance for your graph data.
Production Architecture Overview
A production Dgraph cluster consists of two main components:
- Dgraph Zero: Manages the cluster metadata, assigns shards, and maintains Raft-based consensus.
- Dgraph Alpha: Stores the actual graph data and handles all incoming queries and mutations.
- Ratel: A web-based UI for exploring your graph and managing the cluster.
- Persistent Storage: High-speed SSDs for storage volumes to ensure low-latency I/O.
- Load Balancer: Standard proxy to distribute traffic across your Dgraph Alpha nodes.

dgraph_data:Kubernetes Production Deployment (Recommended)
Use the official Dgraph Helm Chart for a highly available, multi-node cluster.
helm repo add dgraph https://charts.dgraph.io
helm install my-release dgraph/dgraph --namespace database --create-namespaceBenefits:
- High Availability: Automatically runs multiple Zero and Alpha nodes for fault tolerance.
- Scalable Storage: Uses Kubernetes StatefulSets and PersistentVolumeClaims for reliable data management.
- Auto-sharding: Dgraph Zero handles the distribution of shards across your Alpha pods automatically.
Scaling & Performance
- Add More Alphas: To handle more concurrent queries or larger datasets, simply increase your Alpha pod count.
- CPU Isolation: In extreme latency environments, use Kubernetes CPU limits to ensure Alpha pods have dedicated cores.
- Memory Management: Monitor the
lru_cachemetrics to ensure your Alphas have enough RAM for your active working set.
Backup & Disaster Recovery
- Dgraph Snapshots: Use the
/exportendpoint to create a consistent, portable JSON/RDF export of your entire graph. - Point-in-Time Recovery: Dgraph Enterprise supports incremental backups for granular recovery.
- Volume Snapshots: Regularly snapshot your cloud persistent volumes as a baseline for full cluster recovery.
