Amazon S3 Object Lambda now supports using your own code to modify the results of S3 HEAD and LIST API requests

Amazon S3 Object Lambda now supports adding your own code to S3 HEAD and LIST API requests, in addition to S3 GET requests. With S3 Object Lambda, you can modify the data returned by S3 GET requests to filter rows, dynamically resize images, redact confidential data, and much more. Now, you can also use S3 Object Lambda to modify the output of S3 LIST requests to create a custom view of all objects in a bucket and S3 HEAD requests to modify object metadata such as object name and size. With this update, S3 Object Lambda now uses AWS Lambda functions to automatically process the output of S3 GET, HEAD, and LIST requests.
