class GraphqlMigrateExecution::DataloaderAll

This field calls dataloader with some property of object. It can be migrated to use dataload_all(...) and objects.map { |object| ... }.

# Previous:
def my_field
  dataload(Sources::GetThing, object.some_attribute)
end

# New:
def self.my_field(objects, context)
  context.dataload_all(Sources::GetThing, objects.map { |object| object.some_attribute })
end
