I am trying to change the structure of part of my Db, it a part that is getting called pretty frequently, thus I am afraid it is going to cost more than one read per call due to my new nesting nature, I want to nest it under a sub doc due so I can protect the whole sub-col by a premium Until value, will this nesting increase the price of since I am querying deep to 1 level plus checking the premium Until value in rules ? would my single call now considered a double call one for the week and one for the weeks ??
// Call
let collectionRef = collection(db, 'Weeks', id, 'week');
// get a specific doc in that sub-collection.// Db Model
>Solution :
The nesting of a document doesn’t affect how much it costs to read it. One document read is always going to cost the same, no matter what the collection it comes from.
