How to execute a query using the graphql-java engine
How graphql-java maps object data to graphql types
How scalar types work in graphql and how to write your own scalars
How to avoid the dreaded N+1 calls for data and make your graphql system more efficient
Instrumentation allows you to inject code that can observe the execution of a query and also change the runtime behaviours

Often when executing a query you have two classes of data. The data you need immediately and the data that could arrive little bit later.

How you can efficiently look ahead at the selected fields lower in the query
