Backend goes OOM when viewing special datasets

[MichaelBuessemeyer]

Context

When viewing this dataset, the backend goes out of memory pretty fast without the user being able to see any data.

Expected Behavior

The backend should not go out of memory

Current Behavior

One of the many oom errors:

Steps to Reproduce the bug

1. Add the linked dataset to some orga's folder
2. rescan the DS in the dashboard and then view the DS 💥
