Amazon Neptune is a fully managed graph database service by AWS designed to work with highly connected datasets. It supports graph models such as property graphs and RDF (Resource Description Framework), making it ideal for use cases that require complex, highly interrelated data, such as social networks, recommendation engines, fraud detection, and knowledge graphs.
Supports Multiple Graph Query Languages:
TinkerPop Gremlin: Used for property graph traversal.
SPARQL: Used for querying RDF data and linked data.
OpenCypher: Enables property graph queries (currently in preview).
High Performance and Scalability:
Optimized for graph queries with low-latency response times.
Supports millions of queries per second by leveraging high-performance indexing.
Fully Managed:
Handles all administrative tasks such as hardware provisioning, software patching, backups, and scaling.
High Availability:
Built with fault-tolerant features such as Multi-AZ (Availability Zone) deployments and automatic failover.
Provides six replicas across three Availability Zones for enhanced durability.
Seamless Integration with AWS Services:
Integrates with services like AWS Identity and Access Management (IAM), AWS CloudTrail, Amazon S3, AWS Lambda, and Amazon Kinesis for diverse use cases.
Data Security:
Offers encryption at rest using AWS Key Management Service (KMS).
Secures data in transit using SSL/TLS.
Automatic Backups:
Provides continuous backups to Amazon S3 and enables point-in-time recovery (PITR).
ACID Compliance:
Ensures strong consistency and reliable data updates through ACID (Atomicity, Consistency, Isolation, Durability) transactions.
