Create an API Gateway endpoint integrated with Lambda and DynamoDB with X-Ray enabled.
AWS X-Ray records and visualizes requests made by applications, making it a great tool to analyze and debug applications built using a microservices and serverless architecture.
This CDK application demonstrates how to integrate X-Ray SDK in Lambda functions to observe into downstream API calls. This example creates an Amazon API Gateway REST API that uses a Lambda function as the backend to scan a DynamoDB table. The REST API and Lambda function both have X-Ray tracing enabled. X-Ray SDK is also integrated in the Lambda function to observe into the API call to the downstream DynamoDB table.

Cleanup
1. Delete the stack:
npx cdk destroy.2. Confirm the stack has been deleted:
aws cloudformation list-stacks --query "StackSummaries[?contains(StackName,'STACK_NAME')].StackStatus".3. You see a message confirming DELETE_COMPLETE.
