The go-to resource for graph technology details
A multi-model database inspired by OrientDB, supporting graphs, documents, key-value, time-series, and search. Uses RAFT-based replication for high availability.
Protocols HTTP/REST, PostgreSQL wire, Bolt, gRPC, Redis RESP
ArcadeDB also ships MongoDB BSON-protocol and TinkerPop Gremlin plugins (not in our controlled vocabulary / not independently verified here); default ports: HTTP 2480, Postgres 5432, Bolt 7687, gRPC 50051, Redis 6379.
Reach ArcadeDB through the wire protocol that suits your tooling.
