feature

AWS Lambda's recursive loop detection is now available in all commercial AWS Regions, expanding its protective coverage for serverless applications. This guardrail automatically identifies and halts unintended recursive invocations between Lambda functions and services like Amazon S3, SQS, and SNS. It prevents runaway workloads, unexpected billing, and resource consumption caused by misconfigurations or code defects. Enabled by default, the feature notifies users via AWS Health Dashboard and can be disabled for intentional recursive patterns using the PutFunctionRecursionConfig API.
