In this AWS re:Invent 2022 session, AWS Data Hero Alex DeBrie and DynamoDB Senior Principal Engineer Amrith Kumar provide an in-depth look at data modeling concepts for Amazon DynamoDB. They explore how DynamoDB's architecture enables applications to scale from 30 to 300 million customers while maintaining consistent, single-digit millisecond performance. The speakers cover key topics including DynamoDB's infrastructure, data modeling best practices, single-table design, and consistency models. They emphasize the importance of understanding access patterns when designing DynamoDB tables and demonstrate how to leverage features like secondary indexes and transactions. The presentation includes real-world examples and practical advice for optimizing DynamoDB usage in large-scale applications.
