Enabling Streaming between a TargetEndpoint Response and a Backend Service

[cipriangrigoras]

Hi team,

We have the following scenario to which we're trying to find a solution involving Streaming:

• External API provides large response
• Apigee Proxy connects to this API as TargetEndpoint and retrieves the response (200 MB+) using streaming
• How can we pass this large response to our own Backend Service (another TargetEndpoint, that supports streaming) directly from Apigee ?
  1. If we use a Service Callout to a TargetEndpoint, Streaming for it doesn't appear to work and the request that lands on the TargetEndpoint is empty.
  2.  any other way to pipe directly the streaming output from one Backend Service (~external) to another Backend Service (~internal) using Apigee ?

We're using Apigee X.

Let me know if any other info is helpful to describe the scenario we're facing.

Thank you in advance for any info !
