Rockset is a serverless search and analytics engine delivered as a cloud service. One of the company’s use cases is to support SQL on NoSQL data from Amazon DynamoDB and perform real-time analytics. There’s an increasing need for operational analytics and real-time business reporting in organizations, which requires the ability to search transactional data, run aggregations, and join the data with other datasets. Organizations using DynamoDB find it hard to run complex queries for analytics as it’s not designed for scan operations or fetching a large volume of data.

This led the company to architect and integrate DynamoDB and maintain an up-to-date indexed version of DynamoDB in Rockset. Kshitij Wadhwa and Dhruba Borthakur explore how Rockset maintains a real-time sync with DynamoDB and provides fast and complex SQL support over it.

You’ll follow along on the project’s journey and see the challenges the company faced and how it solved them. Kshitij and Dhruba explain the limitations of DynamoDB for building live dashboards, designing a system that bulk loads and then streams updates from DynamoDB in a fault-tolerant fashion, maximizing read throughput from DynamoDB without interfering with existing workloads, continuously monitoring DynamoDB streams without adding cost to the user’s DynamoDB bill while keeping data latency below one second, and building interactive and live dashboards on DynamoDB.

  • A basic understanding of Amazon DynamoDB, SQL, and real-time analytics

What you'll learn
