DynamoDB Single Table Design

This skill covers single table design patterns for DynamoDB, the AWS-recommended approach for modeling complex relationships in a single table.

Core Philosophy

Single table design principles:

• One table to rule them all: Model all entities in a single table
• Overload keys: Use generic pk/sk for flexibility
• Optimize for access patterns: Design around how you query data
• Denormalize when needed: Duplicate data to avoid joins
• Use GSIs strategically: Add secondary indexes for alternate access patterns
