AWS Lambda recursive loop detection now available in Europe Sovereign Cloud
AWS Lambda's recursive loop detection is now supported for functions operating within Europe Sovereign Cloud. This feature automatically identifies and halts unintended recursive invocations between Lambda functions and services like S3, SQS, and SNS, safeguarding against unexpected billing caused by misconfigurations or code defects. It activates by default for functions using supported SDK versions, notifying users via the AWS Health Dashboard upon detection. Users requiring intentional recursive loops can disable this protection using the PutFunctionRecursionConfig API.
