Build a serverless recipe-sharing API with Go and Amazon Aurora DSQL

This article demonstrates building a serverless recipe-sharing REST API in Go using Amazon Aurora DSQL, AWS Lambda, and API Gateway.

• Use UUIDs instead of sequential keys to distribute writes evenly across Aurora DSQL storage nodes
• Authenticate with short-lived IAM tokens instead of stored database passwords via the Aurora DSQL connector
• Enforce referential integrity in application code rather than database constraints for explicit control
• Run DDL and DML statements separately since they cannot be mixed in the same transaction
• Deploy with provided CloudFormation template and deploy.sh script for full serverless infrastructure
• Leverage optimistic concurrency control with automatic retry logic handled by the connector
• Use Go interfaces to abstract database operations for testability and local/Lambda deployment flexibility

The dual-entrypoint pattern enables fast local development with a standard HTTP server while deploying identical code to Lambda, creating a fully serverless architecture that scales on demand with no infrastructure management.
