Datadog has introduced enhancements to its distributed tracing for serverless applications, providing visibility into additional serverless patterns. These improvements include span auto-linking for Amazon S3 and DynamoDB change events, enhanced AWS Step Functions trace propagation, and support for JSONata payloads in state machine definitions. The new features aim to provide comprehensive end-to-end visibility across serverless applications, enabling users to monitor performance, locate affected upstream or downstream services, and troubleshoot issues more effectively.
