Streaming large data set to an endpoint

Hi,
I am using Tyk v.5.9.1 open source version in k8s.
I would like to ask if Tyk can stream data to a specific endpoint.
The data flow would be:

client --> 4GB data (request json body) -> Tyk -> web service endpoint /stream

The web service can handle the 4GB streaming data. Can Tyk also manage this?
What would be the best method to use with the OAS?

Thanks
