Amazon Neptune

AWS fully managed graph database supporting property graph (Gremlin, openCypher) and RDF (SPARQL) models.

Definition

Neptune stores and queries highly connected data such as social networks, recommendation engines, fraud detection and knowledge graphs. It replicates storage across AZs and supports read replicas and a serverless option.

Example

A fraud system uses Neptune to find accounts sharing devices and addresses within three hops.

Exam tip

Relationship-heavy queries (friends of friends, fraud rings) point to a graph database such as Neptune.
