In this post, we present a design for a common technical requirement: ingest data from multiple sources to a target Resource Description Framework (RDF) graph database. Our target is Amazon Neptune, a managed graph database service. RDF is one of two graph models supported by Neptune. The other is Labeled Property Graph (LPG). Each graph […]

You can use Amazon DynamoDB to build internet-scale applications that support user-content metadata and caches that require high concurrency and connections for millions of users and millions of requests per second using the default DynamoDB Standard table class. For example, Amazon.com uses DynamoDB to deliver consistently low latency for mission critical and extreme-scale events such […]
