I'm creating an app where I will store users under all postalcodes/zipcodes they want to deliver to. The structure looks like this:
postalcodes/{{postalcode}}/{{userId}}=true
The reason for the structure is to easily fetch all users who deliver to a certain postal code.
ex. postalcodes/21121/
If all user applies like 500 postalcodes and the app has about 1000 users it can become a lot of records:
500x1000 = 500000
Will Firebase easily handle that many records in data storage, or should I consider a different approach/solution? What are your thoughts?
Kind regards, Elias
