Sample for Project Reactor support

I would like to request a sample / feature of supporting Spring Project Reactor. If the ability exists right now, I would like an example for this.

The issue names Spring Project Reactor but no files, tests, or entry points. Start by locating the existing Spring integration and samples, then determine whether Reactor support already exists. Done should be an agreed, demonstrated sample or support change, but the requested scope is not defined here.
