Hi All, I'm a developer of the open source Ray project ( https://github.com/ray-project/ray) and looking into writing a portable python beam runner on top of Ray. I'm wondering if beam has equal support for writing a portable python runner given that all real runners are in Java (e.g. spark, flink). Also is there any reference implementation of portable python runner or any materials about writing a portable runner that I can take a look at? Thanks!
