ArangoDB

Scalable multi-model database for graphs, documents, and key-values

Document Databases

Overview Highlights Managed products Fit Use cases Tech Tags FAQ

ArangoDB delivers native graph, document, and key-value capabilities with a unified AQL query language, horizontal scalability, high availability, and integrated full-text search for modern data-driven applications.

Overview

Highlights

Native multi-model support (graph, document, key-value)

Integrated ArangoSearch full-text and ranking engine

Horizontal scalability with sharding and automatic failover

Foxx JavaScript microservice framework for data-centric services

Pros

Unified query language simplifies multi-model operations
High-performance C++ core handles large datasets efficiently
Flexible schema-free or schema-validated data modeling
Robust clustering with built-in HA and replication

Considerations

Steeper learning curve for AQL compared to traditional SQL
Enterprise-only features require a paid edition
Memory usage can be high for large indexes
Operational complexity increases with multi-node clusters

Managed products teams compare with

When teams consider ArangoDB, these hosted platforms usually appear on the same shortlist.

Azure Cosmos DB

Fully managed, globally distributed NoSQL database service offering multi-model support with low-latency access worldwide

MongoDB

Document-oriented NoSQL database for flexible data storage

Looking for a hosted option? These are the services engineering teams benchmark against before choosing open source.

Fit guide

Great for

Applications needing combined graph and document queries
Real-time analytics on connected data
Microservice architectures that benefit from embedded JavaScript logic
Enterprises requiring horizontal scaling and high availability

Not ideal when

Simple key-value stores where a dedicated KV database suffices
Projects with strict low-memory constraints
Teams preferring pure SQL relational models
Use cases requiring only on-premise without cloud support

How teams use it

Social network feed generation

Fast traversal of user relationships and content ranking using AQL and ArangoSearch to deliver personalized feeds.

Fraud detection in financial transactions

Combine graph patterns of transaction flows with document attributes to identify anomalous cycles in near real-time.

IoT telemetry storage and query

Store time-series key-value metrics alongside device metadata, enabling flexible queries and alerts via Foxx services.

Product recommendation engine

Leverage multi-model data to match user behavior graphs with product catalogs, delivering ranked suggestions through integrated search.

Frequently asked questions

What query language does ArangoDB use?

ArangoDB uses AQL (ArangoDB Query Language), a SQL-like language that works across documents, graphs, and key-value collections.

Is there a free version?

Yes, the Community Edition is free and fully featured for development and many production workloads.

Can I run ArangoDB in Docker?

Absolutely—official Docker images are provided; start with `docker run -e ARANGO_ROOT_PASSWORD=... -p 8529:8529 -d arangodb`.

How does clustering work?

Data can be sharded across nodes with automatic replication and failover; features like SmartGraphs and OneShard simplify graph clustering.

What languages can I use for client applications?

ArangoDB offers drivers for JavaScript, Python, Java, Go, C#, and many other languages.
