database - How many records / rows / nodes is a lot in Firebase?

Question

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
