PoC: GraphQL Ruby fragment caching

This example demonstrates how we can cache the response fragments in graphql-ruby.

Existing solutions only allow caching resolved values but not all the GraphQL machinery (validation, coercion, whatever).

Caching response parts (in case of Ruby, sub-Hashes) is much more efficient.

Updating a feature branch

First we'll update your local master branch. Go to your local project and check out the branch you want to merge into (your local master branch)

$ git checkout master

Fetch the remote, bringing the branches and their commits from the remote repository. You can use the -p, --prune option to delete any remote-tracking references that no longer exist in the remote. Commits to master will be stored in a local branch, remotes/origin/master

#   size: approximation of the associated memory occupied (based on size/length of value)
#   percent: the proportion of this 'size' relative to the sample's total
