AWS Lambda now detects and stops recursive loops between Lambda and Amazon S3

The article is about a new feature in AWS Lambda that detects and stops recursive loops between Lambda and Amazon S3. It is a preventative measure to avoid unintended usage and billing from runaway workloads caused by customer misconfiguration or code defects.

Specifically, the article covers:

• Lambda recursive loop detection, enabled by default, automatically detects and stops recursive invocations between Lambda and other supported services like Amazon S3.
• When an Amazon S3 bucket triggers a Lambda function, and the processed events are sent back to the same bucket, causing a recursive loop, Lambda will detect and stop it.
• Customers will receive an AWS Health Dashboard notification with troubleshooting steps if a recursive loop is detected.
• The feature is available in all regions where Lambda recursive loop detection is available.
• Customers can use the PutFunctionRecursionConfig API to turn off recursive loop detection if they use intentional recursive loops.
