Class: DynamoDBWriteTestConstruct¶

Defined in: serverless/functions/dynamo-capacity/dynamo-database-write-test-construct.ts:33

CDK Construct for DynamoDB Write Capacity Test Lambda Function

This construct creates a Lambda function that tests DynamoDB write capacity by writing configurable-sized items and measuring consumed WCUs.

Note: DynamoDB permissions are intentionally NOT included in this construct. They should be added separately for workshop/troubleshooting scenarios.
