[self-host, multi-worker] Assigning specific heavy docs to certain workers in multi-worker setup

Hi, does anyone know how to assign specific docs to specific worker instances?

I have the following 2 cases that need to have more specific doc to worker assignments:

  1. Docs that are known to have heavy loads (which can severely affect other lighter docs and may also need higher specced machine)
  2. Docs that need quicker responses (when bunched together with other docs, might affect the response time)

Adding more worker instances may temporarily resolve the issues, but there is a budget constraint to the number of physical instances that can be added. Grouping workers according to the docs use case would really help.

Saw GRIST_WORKER_GROUP in the repo, thought it might have to do with solving the above but couldn’t find how docs can be assigned to which group.

Thanks
