Flask accept request data as a stream without processing?

Question

I have an endpoint in my Flask application that accepts large data as the content. I would like to ensure that Flask never attempts to process this body, regardless of its content-type, and always ensures I can read it with the Rquest.stream interface.

This applies only to a couple of endpoints, not my entire application.

How can I configure this?

The Werkzeug Request object heavily relies on properties and anything that touches request data is lazily cached; e.g. only when you actually access the .form attribute would any parsing take place, with the result cached.

In other words, don't touch .files, .form, .get_data(), etc. and nothing will be sucked into memory either.

I started using stream and don't appear to have any problems.
