Multi Model DBMS Built for Extreme Performance

ArcadeDB is a Multi-Model DBMS (created originally as a fork from OrientDB Open Source project after the acquisition by SAP) with a brand-new engine made of Alien Technology, able to crunch millions of records per second on common hardware with the usage of minimal resources. ArcadeDB is written in LLJ: Low Level Java. It's still Java11+ but only using low level API to use advanced mechanical sympathy techniques and a reduced pressure of the Garbage Collector. It's highly optimized for extreme performance. 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
Vector Embedding

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 can be used as:

Embedded from any language on top of the Java Virtual Machine
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)

For more information, see the documentation.
