Neptune is a fully managed graph database. It’s built for data whose value is in the relationships — social networks, recommendation engines, fraud detection, knowledge graphs.
The tell
When a scenario is about highly connected data and querying relationships (“friends of friends,” “what else did people who bought this buy”), that’s a graph database — Neptune. Relational joins would be slow and awkward; DynamoDB is key-value. Neptune is purpose-built for graph traversal.
