Hi, We're looking into leveraging the cross language pipeline feature in our Beam pipelines on Samza runner. While the feature seems to work well, the PTransform expansion as a standalone service isn't very convenient. Particularly that the Python pipeline needs to specify the address of the expansion service.
I'm wondering why we couldn't embed the expansion service into runner itself. I understand the cross language feature wants to be runner independent, but does it make sense to at least provide the option to allow runner to use the expansion service as a library and make it transparent to the portable pipeline? Thanks, Hai
