S3 Multipart Upload - Event Notifications for UploadPart

No, S3 event notifications do not provide notifications for each individual part upload in a multipart upload workflow.

The S3 event notifications can be configured to notify on the following multipart upload events:

s3:ObjectCreated:Post - When a multipart upload is completed by posting the completed object.

s3:ObjectCreated:Put - When an object is created by performing a regular PUT operation.

s3:ObjectRemoved:Delete - When a multipart upload is aborted by deleting the object.

However, there is no event notification triggered for each successful part upload within a multipart upload workflow. The notifications are sent only after the multipart upload is fully completed or aborted.
