Amazon Neptune graph database introduced a feature allowing openCypher queries to read data directly from Amazon S3 via the neptune.read() procedure, removing the need for multi-step data loads into Neptune. This federation enables dynamic incorporation of external datasets for real-time graph analytics and complex queries involving S3-hosted reference material.
The procedure supports various data types, including Neptune-specific ones like geometry and datetime, and uses IAM credentials for secure access. It is available in all AWS Regions where Neptune operates, facilitating integration of heterogeneous data sources for enhanced graph-based insights and flexibility.
