Research direction
Start with the Graphql README.md and gqlgen Dataloader Docs, then trace the sections event resolver described in the issue. Identify how referenced courses are currently loaded and implement batching for those requests. Done means querying sections with their courses avoids one course query per section.
Written by the indexing model from the issue text.
Description
Overview
Moving part of the dataloader portion from #384 to here.
Currently, if someone queries for a list of sections with their referenced course, our sections event resolver will handle this request by making one query to get the list of sections and then making N more queries for each course. This is the N+1 query problem. Resolve this problem by implementing a dataloader for courses.
