> Within the last year, AWS added a handy Empty button to the S3 console when viewing a bucket. You can click that button and watch the S3 console make API calls on your behalf. > Here's what it does: It calls a LIST on the bucket, pagination through the objects in the bucket 1000 at a time. It calls a DeleteObjects API method, deleting 1000 at a time. > The cost is 1 API LIST call per 1000 objects in the bucket. Delete operations are free, so there's no extra cost there. source: I read the article.
