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 millions of records per second on common hardware with minimal resource usage. ArcadeDB reuses OrientDB's SQL engine (heavily modified) and some utility classes. It's written in LLJ: Low Level Java - still Java21+ but only using low level APIs to leverage advanced mechanical sympathy techniques and reduce Garbage Collector pressure. Highly optimized for extreme performance, it runs from 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 (no joins 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 OrientDB

SQL)

• 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)

• 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 \
           -e ARCADEDB_SETTINGS="-Darcadedb.server.rootPassword=playwithdata -Darcadedb.server.defaultDatabases=Imported[root]{import:https://github.com/ArcadeData/arcadedb-datasets/raw/main/orientdb/OpenBeer.gz}" \
           arcadedata/arcadedb:latest

Pass database settings in ARCADEDB_SETTINGS and any extra JVM flags in JAVA_OPTS: Docker replaces an environment variable rather than appending to it, so keeping the two apart leaves the image's own garbage collector and heap sizing (ARCADEDB_OPTS_GC and ARCADEDB_OPTS_MEMORY) intact. The heap is sized as a percentage of the container memory limit, so docker run -m 512m and a multi-GB production container both work without further tuning. On Java 25 and later server.sh also enables compact object headers (-XX:+UseCompactObjectHeaders), after
