What problem does it solve?

Single-table design is a DynamoDB pattern that avoids many tables by modeling diverse entities (users, posts, metadata) in one table with well-chosen partition and sort keys. This skill explains the approach, key concepts, and practical patterns to design scalable, cost-effective data models.

Core Features & Use Cases

  • Unified data model: model users, posts, and related entities in a single table with generic keys (pk, sk) and carefully chosen GSIs.
  • Access-pattern driven design: Get, Query, and GSI-based lookups built around common queries like "get user profile" or "list a user's posts".
  • Practical guidance: step-by-step patterns for item collections, metadata, and denormalization to support serverless SST apps.

Quick Start

Initialize a DynamoDB single-table schema by defining keys for USER#<id>, POST#<postId>, and METADATA for a given item, then perform a Get on USER#123 PROFILE and a Query for POST# by that user.
