in the documentation, it says to avoid using IDs for tags. Nevertheless, fields are not indexed, so doing a join on them would be painful.
In my case I have two measurements:
reactions, where action has a
uuid and reaction has an
action_uuid for the corresponding action.
Since I want to join actions with reactions, I was putting the two uuids as tags.
Does it make sense or should I prefer fields?
Thanks for the help
