Description

Hi @lgebhardt,

We've encountered the issue with performance during include has many relations.

While we are including has many relations our resource is referencing to records_for(association_name) method which fetches all the relation data and then serializer while fetching links in relation (resource_serializer.rb:300) hits again the same has many relation which referrers again to records_for(association_name) code.

It seems to be redundant and it has an impact on the performance of the end-point.

Research direction

Start by tracing records_for(association_name) and the has-many path in resource_serializer.rb around line 300. Confirm where the included relation is fetched and where link serialization fetches it again; done means the redundant fetch is removed and endpoint performance is improved.
