When to use
Optimised for: relationship modeling + reasoning + governance over pure vector
Anti-fit: not for purely-vector or simple-RAG use cases (graph adds setup cost)
Pros & cons
Pros
Multi-model (graph + document + KV) in one engine — useful when memory crosses paradigms without managing multiple databases.
Cons
Multi-model adds complexity vs single-purpose engines; smaller community than Neo4j or MongoDB.
Claims & capabilities
Rated #1 graph DB Fall 2025. Open-source + ArangoGraph cloud.
