Can Ktor handle resumable uploads out-of-the-box?

[DassieKlip]

I need to upload files to a Google bucket, using a signed URL, where files have a maximum size of 300 MB.

My client is configured with a 30s request timeout, so I've been encountering timeouts when uploading files approaching the max size.

Timeouts are going to be inevitable, regardless of any reasonable timeout configuration, so the solution seems to be resumable uploads.

Does Ktor have out-of-the-box support for resumable uploads?
Or do I have to manually read the data from the input stream, keep track of how many bytes were uploaded already, and upon timeout make another request with the headers adjusted accordingly?

Or am I looking at this totally wrong?

Unfortunately, Ktor doesn't provide an out-of-the-box solution for resumable uploads and downloads.
