KV caching does not appear to work about workers-graphql-server

[devinellis]

In my case, I wonder if its because I am attempting to cache POST requests to a RESTDataSource?

@devinellis I'm doing a get, but I think I've set all the required variables in the readme, but I also don't know of a way I can debug it easily without pushing it out first

I've got a little more information about this bug. Cache is being read but never written.

According to this the interface is super simple to implement, and I believe it's connected correctly. Seems possible I need to pass something in the request header to get caching to write correctly or something, but I cannot figure out where

welp, nevermind @devinellis. Looking through this, apollo will cache based up the RESTDataSource response Cache-Control headers. In our case, not in a position to request that those change, so you can enforce it inside the resolvers.js file like this:

this.get('/v1/user', null, { cacheOptions: { ttl: 60 } })

We're setting these via environment variables, but it may be worth a callout in the docs here, I was completely unaware that the RESTDataSource acted like this.
