Module: Pipeloader::ARPatch

Defined in:
lib/pipeloader/ar_patch.rb

Overview

Monkey-patch: while a Pipeloader dataloader is active (i.e. during GraphQL response building), route SELECTs through the pipelining Source instead of executing them synchronously. Everything else falls through to AR untouched.
