Dynamodb
This gives Claude everything it needs to work with DynamoDB, from table design to query optimization. The source covers the fundamentals well: partition and sort keys, GSIs versus LSIs, batch operations, and conditional writes with code examples in both boto3 and AWS CLI. What's genuinely useful here is the emphasis on access pattern driven design and single-table patterns, which is how you actually want to think about DynamoDB but isn't always obvious when you're coming from relational databases. The troubleshooting section addresses the real pain points like throttling and hot partitions. If you're building anything that needs to scale reads and writes independently, or you're tired of fighting with RDS connection pools, this covers the practical knowledge for getting DynamoDB right.

Table of Contents
Core Concepts
Keys
| Key Type | Description |
|---|---|
| Partition Key (PK) | Required. Determines data distribution |
| Sort Key (SK) | Optional. Enables range queries within partition |
| Composite Key | PK + SK combination |
Secondary Indexes
| Index Type | Description |
|---|---|
| GSI (Global Secondary Index) | Different PK/SK, separate throughput, eventually consistent |
| LSI (Local Secondary Index) | Same PK, different SK, shares table throughput, strongly consistent option |
Capacity Modes
| Mode | Use Case |
|---|---|
| On-Demand | Unpredictable traffic, pay-per-request |
| Provisioned | Predictable traffic, lower cost, can use auto-scaling |
