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

FedShard sharding architecture handles trillion-triple scale; strong RDF + reasoning support for semantic-web workloads.

Cons

Niche product with a small community; tooling and docs lag mass-market alternatives.
