Question
A company is building a mobile application to provide purchase recommendations to its customers. The company wants to use a graph database as part of the purchase recommendation engine. Which AWS database service should the company choose?
A. Amazon DynamoDB
B. Amazon Aurora
C. Amazon Neptune
D. Amazon DocumentDB (with MongoDB compatibility)
Answer
C. Amazon Neptune
Explanation
Amazon Neptune is a service that provides a fully managed graph database that supports both property graphs and RDF graphs. It can be used to build applications that work with highly connected datasets, such as purchase recommendations, social networks, fraud detection, and knowledge graphs.
Amazon Neptune is a fully managed graph database service offered by AWS, specifically designed to handle highly connected datasets. It supports graph models such as property graphs and RDF (Resource Description Framework), as well as their respective query languages, including Apache TinkerPop Gremlin, openCypher, and SPARQL. These features make it ideal for use cases like recommendation engines, fraud detection, knowledge graphs, and social networks.
In the scenario described, where a company aims to build a purchase recommendation engine using a graph database, Amazon Neptune is the most suitable option because:
- Purpose-Built for Graph Data: Neptune is optimized for storing billions of relationships and querying them with millisecond latency. This makes it highly effective for analyzing connections and patterns in data.
- Scalability and Performance: It can scale up to 128 TiB of storage per cluster and handle over 100,000 queries per second. This ensures it meets the demands of large-scale applications.
- Integration with AWS Ecosystem: As part of AWS, Neptune integrates seamlessly with other services like Amazon S3 for backups and analytics tools for insights.
- Ease of Management: Being fully managed, it eliminates the need for tasks like hardware provisioning or software patching.
Other options are less suitable
Amazon DynamoDB (A): While it is a NoSQL database capable of handling key-value and document data models, it is not optimized for graph-specific workloads.
Amazon Aurora (B): Aurora is a relational database service designed for SQL-based applications, not graph use cases.
Amazon DocumentDB (D): This service is tailored for document-based databases (e.g., MongoDB compatibility) and does not support graph models or query languages.
Thus, Amazon Neptune is the clear choice for implementing a graph database to power a recommendation engine.
