ArcadeDB is an open-source, Apache 2.0 licensed multi-model DBMS written in Java that natively stores graphs, documents, key-value pairs, full-text search, vectors, and time-series in a single ACID-compliant engine. It supports multiple query languages including SQL, Cypher, Gremlin, GraphQL, and the MongoDB and Redis protocols, and can run embedded in a JVM or as a distributed server.

Use cases

  • store graph, document, and vector data in one database instead of polyglot persistence
  • run similarity search over vector embeddings for AI/RAG applications
  • query a graph database with Cypher or Gremlin
  • embed a high-performance database directly inside a Java application
  • replace OrientDB with an actively maintained fork
  • connect via MongoDB, Redis, or Postgres wire protocols from existing clients
  • run a distributed ACID database on Docker or Kubernetes

When to choose

  • you need multiple data models (graph, document, key-value, vector, time-series) without running several databases
  • you want an OrientDB successor with active development and Apache 2.0 licensing
  • you need vector similarity search alongside graph or document workloads
  • you want embedded-mode database access in the JVM with zero network overhead
  • your clients already speak MongoDB, Redis, or Postgres protocols

When to avoid

  • you need a single-model database with a large ecosystem of specialized tooling (e.g., pure Postgres or Neo4j)
  • your stack is not JVM-based and you only need remote access with no Java API
  • you require managed cloud hosting rather than self-hosted deployment
  • you need extremely mature enterprise support without a paid subscription plan
