If anyone is interested in prior art, take a look at Google Cloud Storage&#x27;s resumable uploads: <a href="https:&#x2F;&#x2F;cloud.google.com&#x2F;storage&#x2F;docs&#x2F;json_api&#x2F;v1&#x2F;how-tos&#x2F;upload#resumable" rel="nofollow">https:&#x2F;&#x2F;cloud.google.com&#x2F;storage&#x2F;docs&#x2F;json_api&#x2F;v1&#x2F;how-tos&#x2F;up...</a><p>It&#x27;s very domain specific and relies on GCP&#x27;s JSON API so probably isn&#x27;t suitable to apply broadly.
