AWS Neptune Analytics: Merging Vector Search and Graph Data for Enhanced AI Applications

May 17, 2024

In the realm of AI, a debate has been brewing over the superiority of graph versus vector databases for uncovering truthful information in generative AI applications. Amazon Web Services (AWS) has taken a groundbreaking step by merging these two powerful capabilities in its new service, Neptune Analytics, announced at AWS re:Invent. Swami Sivasubramanian, vice president of data and machine learning at AWS, emphasized the innovative combination of graph analytics and vector search in this tool. Neptune Analytics enables customers to delve into existing Neptune graph data or data lakes on S3 storage, utilizing vector search for key insights. The integration of these two methodologies facilitates the discovery of intricate relationships within the graph, enhancing analytical capabilities.

Neptune Analytics is designed as a fully managed service, allowing users to focus on problem-solving through queries and workflows, while AWS handles the infrastructure. This service dynamically allocates compute resources based on the graph's size and swiftly loads data in memory for rapid query execution. Available as a pay-as-you-go service in various AWS regions, Neptune Analytics offers a practical and flexible solution for diverse applications.

At its core, Amazon Neptune is a graph analytics and serverless database, ideal for managing interactive graph applications of any scale. This fully managed graph database enables searching and querying billions of relationships in milliseconds, offering high-availability configurations and dynamic scalability. The storage is fault-tolerant, self-healing, and automatically scales, ensuring consistent performance and high resiliency. Users benefit from popular graph query languages like Apache TinkerPop Gremlin, W3C’s SPARQL, and openCypher, which simplify the creation of powerful and efficient queries for connected data.

Neptune Analytics expands upon these capabilities by supporting graph analytics, graph algorithms, and vector search of graph data stored in Amazon S3 buckets or a Neptune database. This allows for the analysis of tens of billions of relationships in mere seconds, catering to the most demanding graph analytic workloads. Additionally, Neptune ML integrates with Amazon SageMaker to train graph neural networks (GNNs), offering fast and accurate predictions based on graph data. This integration supports real-time predictions and enables continual learning without the need for frequent retraining of the ML models.

The serverless option in Neptune Analytics provides an on-demand deployment that automatically adjusts database capacity based on application needs, potentially saving up to 90% in database costs compared to peak capacity. The database offers high throughput and low latency for graph queries, easy scalability of compute resources, and automatic scaling of storage. Additionally, up to 15 low-latency read replicas can be created, enhancing read throughput and reducing replica lag times.

One of the most innovative aspects of Neptune Analytics is its application in generative AI. Vector search simplifies the building of ML-augmented search experiences and generative AI applications. By combining data from specific application domains with similarity searches on vector embeddings, Neptune Analytics provides a cost-effective and easily manageable solution for generative AI applications. This feature is particularly beneficial for augmenting large language models with domain-specific context, integrating graph queries, and conducting low-latency similarity searches on embeddings.

In summary, AWS Neptune Analytics represents a significant advancement in AI database management. By fusing the strengths of vector search and graph data, Neptune Analytics not only simplifies complex data analysis but also opens new horizons for generative AI applications. Its fully managed, scalable, and flexible nature makes it an invaluable tool for a wide range of industries and use cases, driving forward the potential of AI in data analytics.
