Simplify real-time analytics with zero-ETL from Amazon DynamoDB to Amazon SageMaker Lakehouse


At AWS re:Invent 2024, we launched a no code zero-ETL integration between Amazon DynamoDB and Amazon SageMaker Lakehouse, simplifying how organizations deal with knowledge analytics and AI workflows. This integration alleviates the standard challenges of constructing and sustaining advanced extract, rework, and cargo (ETL) pipelines for reworking NoSQL knowledge into analytics-ready codecs, which beforehand required important time and assets whereas introducing potential system vulnerabilities. Organizations can now seamlessly mix the energy of DynamoDB in dealing with speedy, concurrent transactions with fast analytical processing by the zero-ETL integration. For instance, an ecommerce platform storing consumer session knowledge and cart data in DynamoDB can now analyze this knowledge in close to actual time with out constructing customized pipelines. Gaming corporations utilizing DynamoDB for participant knowledge can immediately analyze consumer conduct as occasions happen, enabling real-time insights into recreation stability and participant engagement patterns.

The zero-ETL functionality makes use of built-in change knowledge seize (CDC) to routinely synchronize knowledge updates and schema modifications between DynamoDB and SageMaker Lakehouse tables. Through the use of Apache Iceberg format, the combination gives dependable efficiency with ACID transaction assist and environment friendly large-scale knowledge dealing with. Information scientists can prepare ML fashions on recent knowledge and knowledge analysts can generate studies utilizing present data, with typical synchronization latency in minutes slightly than hours.

On this put up, we share how you can arrange this zero-ETL integration from DynamoDB to your SageMaker Lakehouse setting.
