AWS Launches Neptune Analytics for Enhanced Graph and Vector Search

AWS RE:Invent 2023
AWS RE:Invent 2023

In a significant development, Amazon Web Services (AWS) announced the launch of Neptune Analytics at the AWS re:Invent event. This innovative service is a strategic combination of graph and vector database technologies, aimed at enhancing data analysis in generative AI applications.

The Debate in AI Databases
There has been an ongoing debate in AI circles regarding the superiority of database types – graph versus vector databases. Each type has its strengths and weaknesses. Vector databases are excellent for managing and querying high-dimensional data crucial for machine learning, while graph databases excel in mapping relationships between data points. However, vector databases often struggle with dimensionality, and graph databases face scalability challenges.

AWS’s Strategic Integration
Addressing these challenges, AWS decided to merge the best of both worlds. Swami Sivasubramanian, Vice President of Data and Machine Learning at AWS, highlighted the service’s ability to analyze massive amounts of graph data with the precision of vector search. This integration allows users to discover relationships in their graph data more efficiently, combining these two technologies to cover each other’s limitations.

How Neptune Analytics Works
Neptune Analytics is designed to analyze existing Neptune graph data or data lakes on AWS’s S3 storage. By storing graph and vector data together, it enhances the discovery of relationships within the data. It’s a fully managed service, which means AWS takes care of the infrastructure, allowing users to focus on solving problems through queries and workflows. The service automatically allocates compute resources based on the size of the graph and loads data in memory to execute queries swiftly.

Impact and Availability
Ray Wang, the founder and principal analyst at Constellation Research, views Neptune Analytics as a clever combination of the two technologies. By merging them, AWS addresses the weaknesses inherent in each, creating a more robust and scalable solution for data analysis. Neptune Analytics is now available as a pay-as-you-go service in several AWS regions, including the US East (Ohio, N. Virginia), US West (Oregon), Asia Pacific (Singapore, Tokyo), and Europe (Frankfurt, Ireland), marking a significant milestone in the field of data analytics.


Neptune Analytics represents a significant advancement in the way we approach data analysis in AI. By harmonizing the strengths of graph and vector databases, AWS is setting a new standard in the industry, offering a more efficient, powerful, and scalable solution for handling complex data.
