3. yes you can use Relay i believe. I've never tried it but i don't see why not, i believe it is relay compliant as graphcool supports relay and eventually Prisma will power that. Not to mention that when you look at the generated code, it seems to have the edges/nodes that relay needs (although im not super familiar with Relay)
