Amazon DynamoDB

DynamoDB is a fully managed, serverless, key-value NoSQL database designed to run high-performance applications at any scale (Single-digit millisecond latency).

When to Use

• Serverless Apps: The default DB for AWS Lambda.
• Infinite Scaling: Handles petabytes of data without maintenance.
• Shopping Carts / Sessions: High throughput, simple key access.

Quick Start (AWS SDK v3)

import { DynamoDBClient, PutItemCommand } from "@aws-sdk/client-dynamodb";
