AWS Lambda Recursive Loop Detection Now Available in Europe Sovereign Cloud
AWS Lambda's recursive loop detection feature is now live in Europe Sovereign Cloud, automatically catching and stopping those pesky recursive invocations that drain your wallet. The system detects misconfigured event chains between Lambda and services like S3, SQS, and SNS, then kills the loop and alerts you via AWS Health Dashboard—though you can disable it if your recursive loops are intentional.
