Relay Notes
===========

 - Define a schema, that is used for _both_ server side endpoint setup & frontend graphql compilation
 - node only for now, some graphql ports
 - Relay has a strict specification of how a graphql schema is set up: https://facebook.github.io/relay/docs/graphql-relay-specification.html

 - tree children are called "plural links" (see _writePluralLink())

Frequently asked questions:

• Why shouldn't i use mysql? / mongo?
• Should I use jinja, I read it's faster?
• Should I use sqlalchemy, I read it's superior?
• How do i make this thing happen in parallel/not wait for xxx to finish?
• Why does django ask for a default? (But my table has no data in it wtf django!?!)
  • FunkyBob | I think, perhaps, it's time I wrote a blog post on "why does a migration adding a field need a default?"
• Why do I need to commit my migrations? Why can't I just run makemigrations on the server?
• migrations are source, makemigrations is a helper which takes you part way
• i've seen people accidentally lose their migrations on production…  oops now what?
