Multi Model DBMS Built for Extreme Performance

ArcadeDB is a Multi-Model DBMS created by Luca Garulli, the same founder of OrientDB,after SAP's acquisition. Written from scratch with a brand-new engine made of Alien Technology, ArcadeDB is able to crunch millionsof records per second on common hardware with minimal resource usage. ArcadeDB reuses OrientDB's SQL engine (heavily modified) andsome utility classes. It's written in LLJ: Low Level Java - still Java21+ but only using low level APIs to leverage advancedmechanical sympathy techniques and reduce Garbage Collector pressure. Highly optimized for extreme performance, it runsfrom a Raspberry Pi to multiple servers on the cloud.

ArcadeDB is fully transactional DBMS with support for ACID transactions, structured and unstructured data, native graph engine (nojoins but links between records), full-text indexing, geospatial querying, and advanced security.

ArcadeDB supports the following models:

• Graph Database (compatible with Neo4j Cypher, Apache Tinkerpop Gremlin and OrientDB SQL)
• Document Database (compatible with the MongoDB driver + MongoDB queries and OrientDBSQL)
• Key/Value (compatible with the Redis driver)
• Search Engine
• Time Series (with InfluxDB Line Protocol, Prometheus remote_write/read, and PromQL support)
• Vector Embedding
• Geospatial

ArcadeDB understands multiple languages:

• SQL (from OrientDB SQL)
• Neo4j Cypher (Open Cypher)
• Apache Gremlin (Apache Tinkerpop v3.7.x)
• GraphQL Language
• MongoDB Query Language

ArcadeDB key capabilities:

• 70+ Built-in Graph Algorithms — Pathfinding, centrality, community detection, link prediction, graph embeddings, and more — all available out of the box
• Parallel Query Execution — SQL queries leverage multiple CPU cores for faster execution on large datasets
• Materialized Views — Pre-computed query results stored and automatically maintained
• MCP Server — Built-in Model Context Protocol server for AI assistant and LLM integration
• AI Assistant — Integrated AI assistant in Studio (Beta) for query help and database management
• Geospatial Indexing — Native spatial queries and proximity searches with geo.* SQL functions
• TimeSeries — Columnar storage with Gorilla/Delta-of-Delta compression, InfluxDB/Prometheus ingestion, PromQL queries, Grafana integration
• Hash Indexes — Extendible hashing for faster exact-match lookups alongside LSM-Tree indexes

ArcadeDB can be used as:

• Embedded from any language on top of the Java Virtual Machine
• Embedded from Python via bindings: arcadedb-embedded-python
• Remotely by using HTTP/JSON
• Remotely by using a Postgres driver (ArcadeDB implements Postgres Wire protocol)
• Remotely by using a Redis driver (only a subset of the operations are implemented)
• Remotely by using a MongoDB driver (only a subset of the operations are implemented)
• By AI assistants via the built-in MCP Server (Model Context Protocol)

For more information, see the documentation.

• Knowledge Graphs — co-authorship and citation networks with full-text search
• Graph RAG — retrieval-augmented generation with LangChain4j and Neo4j Bolt
• Fraud Detection — graph, vector, and time-series signals with Cypher
• Real-time Analytics — IoT and service monitoring with time-series
• Social Network Analytics — materialized view dashboards with polyglot queries
• Supply Chain — multi-tier visibility with PostgreSQL protocol and JavaScript

Getting started in 5 minutes

Start ArcadeDB Server with Docker:

docker run --rm -p 2480:2480 -p 2424:2424 \
           -e JAVA_OPTS="-Darcadedb.server.rootPassword=playwithdata -Darcadedb.server.defaultDatabases=Imported[root]{import:https://github.com/ArcadeData/arcadedb-datasets/raw/main/orientdb/OpenBeer.gz}" \
           arcadedata/arcadedb:latest

Now open your browser on http://localhost:2480 and play with ArcadeDB Studio and theimported OpenBeer database to find your favorite beer.

ArcadeDB is cloud-ready with Docker and Kubernetes support.

You can also download the latest release, unpack it on your local hard drive and start the server with bin/server.sh or bin/server.bat for Windows.

Releases

There are four variants of (about monthly) releases:

• full - this is the complete package including all modules
• minimal - this package excludes the gremlin, redisw, mongodbw, graphql modules
• headless - this package excludes the gremlin, redisw, mongodbw, graphql, studio modules
• base - core engine, server, and network only — excludes all optional modules (console, gremlin, studio, redisw, mongodbw, postgresw, grpcw, graphql, metrics)

The nightly builds of the repository head can be found here.

You can also build a custom distribution with only the modules you need using the Custom Package Builder:

curl -fsSL https://github.com/ArcadeData/arcadedb/releases/download/26.3.1/arcadedb-builder.sh | \
  bash -s -- --version=26.3.1 --modules=gremlin,studio

Available optional modules: console, gremlin, studio, redisw, mongodbw, postgresw, grpcw, graphql, metrics. The builder supports interactive mode, Docker image generation, and offline builds from local Maven repositories.

Java Versions

Starting from ArcadeDB 24.4.1 code is compatible with Java 21.

Java 21 packages are available on Maven central and docker images on Docker Hub.

We also support Java 17 on a separate branch java17 for those who cannot upgrade to Java 21 yet through GitHub packages.

To use Java 17 inside your project, add the repository to your pom.xml and reference dependencies as follows:

    <repositories>
        <repository>
            <name>github</name>
            <id>github</id>
            <url>https://maven.pkg.github.com/ArcadeData/arcadedb</url>
        </repository>
    </repositories>
    <dependencies>
      <dependency>
          <groupId>com.arcadedb</groupId>
          <artifactId>arcadedb-engine</artifactId>
          <version>26.3.1-java17</version>
      </dependency>
    </dependencies>

Docker images are available on ghcr.io too:

docker pull ghcr.io/arcadedata/arcadedb:26.3.1-java17
