Hi Guys,
Wouldn't it make sense to extend this PR to allow streaming uploads to other cloud providers too? Right now it adds the abstraction, but implementation is limited to Azure only.

I have the same question, specifically so we can use with AWS

Hi!
Any chance to close this ticket any time soon? We're waiting for the feature and need to make a decision to either wait or workaround this limitation.

@johanra Thanks for the contribution
@wgruszczyk @marcinfigiel @scprek I am going to merge this and it will be part of 4.7.0. We can add support to other cloud vendors later.
