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
Managed graph database with vector + graph hybrid for AWS-native architectures; first-class integration with Bedrock and SageMaker.
Cons
AWS-only; vector + graph hybrid is newer than dedicated competitors; pricing complexity around graph queries.
Claims & capabilities
Native graph-memory + vector search managed by AWS.
