apollo-studio-tracing

This gem extends the GraphQL Ruby gem to add support for sending trace data to Apollo Studio. It is intended to be a full-featured replacement for the unmaintained apollo-tracing-ruby gem, and it is built HEAVILY from the work done within the Gusto apollo-federation-ruby gem as well an exploratory branch created here.

       apollo_tracing_enabled: Rails.env.production?,
     }
     # ...
   end
