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.

Benchmarks

Backport Rails 6 per-environment credentials to Rails 5.2

Rails PR: rails/rails#33521

This patch makes it possible to use per-environment credentials (i.e., config/credentials/staging.yml.enc) in Rails 5.2.

Installation

Drop backport_rails_six_credentials.rb and backport_rails_six_credentials_command.rb somewhere, for example, into the lib/ folder
Add this line to config/application.rb:

Railsy Rails Events Store

Since our architecture is modularized, we need a way for our components/engines to communicate with each other.

We do this by adding a pub/sub (or event sourcing) layer to our application via Rails Event Store.

We do not use RES directly but through the railsy-events engine, which wraps RES functionality and provide its own API. That would allow us to replace RES in the future (if necessary) without changing our application code.
