DynamoDB Schema Design for E-Commerce

Unlike traditional SQL, DynamoDB design revolves around access patterns. For e-commerce, you’ll design tables around:

• User-centric access (userID as partition key)

• Product lookup (productID or category)

• Order tracking (orderID + timestamps)

  Example schema:

  json

  CopyEdit

  {
"PK": "USER#123",
"SK": "ORDER#456",
"orderStatus": "shipped",
"orderDate": "2025-08-04",
"items": [ ... ]
}

  Performance Tuning Tips

  • Use GSIs and LSIs smartly for multiple access patterns

  • Apply DAX (DynamoDB Accelerator) for read-heavy operations

  • Use BatchGetItem and BatchWriteItem for cost-effective bulk operations

  • Use On-Demand Mode during sales peaks like Black Friday
