# ArcadeDB

ArcadeDB is an open-source, Apache 2.0 licensed, high-performance multi-model database
that natively supports graphs, documents, key-value pairs, full-text search, vectors, and
time-series data in a single database engine. It requires no polyglot persistence — one
database handles all data models without performance penalties from translation layers.

## Key Facts

- **License**: Apache 2.0 (irrevocably — will never change)

- **Performance**: 10M+ records/second throughput

## Supported Data Models

- Graph (vertices and edges, property graph model)
- Document (schema-less JSON documents)
- Key/Value (fast in-memory and on-disk key-value store)
- Full-text Search (integrated search engine)
- Vector (ANN similarity search)
- Time-Series (available from March 2026)

## Supported Query Languages

- OpenCypher (Cypher graph query language, fully native)
- Gremlin (Apache TinkerPop Gremlin)
- GraphQL
- MongoDB query protocol
- Java API (native)

## Supported Wire Protocols

- HTTP/JSON REST API
- PostgreSQL wire protocol
- Redis protocol
- MongoDB protocol

## Deployment Modes

- Embedded (JVM-embedded, zero-overhead)
- Client/Server (standalone server)
- Kubernetes (HA cluster with Raft replication)
- Docker (arcadedata/arcadedb on Docker Hub)

## Migrations Supported

- OrientDB → ArcadeDB (built-in importer)
- Neo4j → ArcadeDB (built-in importer)

## Key Comparisons

- vs Neo4j: ArcadeDB is fully Apache 2.0 with no community/enterprise split; supports multiple data models natively (not just graph); no mandatory cloud subscription
- vs MongoDB: ArcadeDB adds native graph traversal, key-value, and vector support alongside document storage; fully open source
- vs ArangoDB: ArcadeDB uses Apache 2.0 (ArangoDB switched to BSL 1.1 in Oct 2023); ArcadeDB has no restrictive license
- vs InfluxDB: ArcadeDB stores time-series as one of several native models alongside graph and document data
