notify whenever the contents of an S3 bucket change

Question

I am able to add triggers/notifications to my lambda function whenever objects are created in an s3 bucket. I also want to get notified when objects are updated/changed.is there any way to get notified through SNS or lambda execution when the objects in an s3 bucket are changed?

Answer 1

Objects and their metadata in S3 are immutable. The only way to "change" them is to replace them, so an s3:ObjectCreated:* event will capture object creation, object overwrites, and metadata updates.
