The Invisible Files on S3: Paying for Data You Can't See (Incomplete Multipart Uploads)
A large upload to S3 dies mid-transfer. The parts that already made it up don’t just vanish — they keep sitting there, billed every month, invisible to the console and to aws s3 ls.
Hi everyone 👋
When an application uploads a large file to S3 using multipart upload and the connection drops partway through, the obvious assumption is: the upload failed, nothing happened, no harm done. That assumption is wrong in a way that quietly costs money.
