Akka HTTP and Akka streams - using Flows with high level routes API

This question has been asked for older versions of Akka Streams & Akka HTTP. akka-http: complete request with flow the problem with this answer is for each flow you need to materialise a new flow for each request which is not cheap.

A year later in the latest version what is the best way to integrate a flow with the routes DSL?

Again I have a complex Flow I'd like to add to a route, if I map the flow to a Flow[HttpRequest, HttpResponse, _] could I complete a route with this flow? Is there a better way or is the only way to use the low level API?

If thats the case whats the best way to do route mapping?

You are still required to materialize a new flow if you want to leverage Akka Streams DSL from a high-level Akka HTTP directive.

The good news is that Akka 2.5 changed the guts of the ActorMaterializer quite a bit, allegedly improving its performance by 3-4x.

Faster and more flexible Akka Streams materializer, which matters for short lived streams, such as HTTP requests.
