Amazon says its graph database Neptune is now Generally Available, though only in the US and EU. Neptune is a fully managed service that can be used to create relationship graphs of highly connected datasets.
Neptune is based on a purpose-built, high-performance graph database engine optimized for storing billions of relationships and querying the graph with milliseconds latency. It supports two open standards for describing and querying graphs - Apache TinkerPop3 style Property Graphs queried with Gremlin, and Resource Description Framework (RDF) queried with SPARQL. Gremlin is a graph traversal language where a query is a traversal made up of discrete steps following an edge to a node, while SPARQL is a declarative language based on Semantic Web standards from W3C. Data can be imported from S3, and for the Resource Description Framework (RDF) graph model, Neptune supports Turtle, N-Triples, N-Quads, and RDF/XML serializations. Property graphs are limited to CSV.
The development team for Neptune has created some sample repos that you can try to see how it works, including an example of building a collaborative filtering recommendation engine for video game preferences.
Neptune is designed to be highly available, with read replicas, point-in-time recovery, continuous backup to Amazon S3, and replication across Availability Zones. The version that has been made generally available has a few changes from the preview. Apart from performance improvements, the main changes are that it now comes with support for AWS CloudFormation, and has AWS Command Line Interface and SDK support. CloudFormation is a service that can be used to model and set up your Amazon Web Services resources. You create a template that describes all the AWS resources that you want and AWS CloudFormation handles the provisioning and configuring those resources for you. The other change to the GA version is that it has support for IAM roles with bulk loading from Amazon Simple Storage Service (S3)
