AWS Lambda function loop all files in a s3 bucket

For AWS Lambda, I can easily add a s3 object trigger on new objects create event. In other words, any new update/upload file will trigger to run my lambda function.

TL;DR Only on creation, deletion, or RRS object lost.

Currently, Amazon S3 can publish the following events:

A new object created event—Amazon S3 supports multiple APIs to create objects. You can request notification when only a specific API is used (e.g., s3:ObjectCreated:Put) or you can use a wildcard (e.g., s3:ObjectCreated:*) to request notification when an object is created regardless of the API used.

An object removal event—Amazon S3 supports deletes of versioned and unversioned objects. For information about object versioning, see Object Versioning and Using Versioning.

You can request notification when an object is deleted or a versioned object is permanently deleted by using the s3:ObjectRemoved:Delete event type. Or you can request notification when a delete marker is created for a versioned object by using s3:ObjectRemoved:DeleteMarkerCreated. You can also use a wildcard s3:ObjectRemoved:* to request notification anytime an object is deleted. For information about deleting versioned objects, see Deleting Object Versions.

A Reduced Redundancy Storage (RRS) object lost event—Amazon S3 sends a notification message when it detects that an object of the RRS storage class has been lost.
