🕸️Amazon Neptune

NEW

Also known as: Neptune

A managed graph database service supporting RDF and property graph models with SPARQL and Gremlin.

DESCRIPTION

Amazon Neptune is a fully managed graph database that supports both RDF with SPARQL and property graphs with Gremlin. It is optimized for highly connected data and low-latency graph traversals at scale. Neptune integrates with AWS security, backups, and high availability features. Typical use cases include knowledge graphs, fraud detection, recommendation engines, and network security. Neptune ML allows graph ML workflows leveraging Amazon SageMaker.

ALTERNATIVE DEFINITIONS

TOP QUESTIONS

When should I use Amazon Neptune over a relational database?

Choose Neptune when traversing complex, highly connected relationships is the primary workload, such as knowledge graphs and fraud rings.

Category: Decision

What graph models does Amazon Neptune support?

It supports RDF with SPARQL and property graphs with Gremlin, enabling flexibility across graph paradigms.

Category: Feature

How does Neptune scale for large graphs?

It supports storage of billions of relationships with read replicas, fast snapshots, and millisecond-latency queries for graph traversals.

Category: Performance

What are common Neptune use cases?

Knowledge graphs, recommendations, fraud detection, network security analytics, and identity graphs are common scenarios.

Category: UseCase

How is security managed in Neptune?

IAM, VPC isolation, encryption at rest and in transit, and fine-grained SPARQL or Gremlin endpoint access controls secure workloads.

Category: Security

How do I choose between SPARQL and Gremlin in Neptune?

Use SPARQL for RDF/semantic data and standards alignment; use Gremlin for property graph traversals and imperative-style path queries.

Category: Comparison

What is Neptune ML?

It integrates graph ML powered by Amazon SageMaker to run node classification, link prediction, and other graph learning tasks.

Category: Feature

What are notable competitors to Amazon Neptune?

Neo4j and JanusGraph are key alternatives for property graphs; Cosmos DB Gremlin API is also comparable in the cloud.
