Better support for async connections about graphql-relay-js

[wincent]

Can you use connectionFromPromisedArraySlice to avoid resolving the entire entire set?

Not really, it doesn't easily work out-of-the-box - I believe you have to write the logic which calculates the correct sliceStart accounting for whatever args are passed, which ends up duplicating logic from within connectionFromArraySlice

I ended up doing this, takes advantage of the fact that cursors are soley based on the offset and not whatever the array contains: https://github.com/clayallsopp/graphqlhub/pull/29/files; would be happy to open a PR to merge it into graphql-relay-js if its a thing that might be useful for others, but totally happen to just close this too

@clayallsopp have you figured out a clean way to deal with this?

I too have a similar case where it's easier for me to fetch exactly the data I need instead of fetching all the data and having the library trim the data after the fact. I think this is rather common (in my case, request a slice of the database collection instead of the entire thing)
