[REQUIRED] Please describe the question here:

The billing documentation is quite clear regarding what actions get billed, but I just want to make sure I understand the specific instance of writing a whole object to Firestore correctly.

When I have an object of a class that is marked with "FirestoreData" with a few "FirestoreProperty" properties and I then call "SetAsync(thatObject)", how is billing handled?

• Does it count as one write (assumption: "Set" is only called once) or
• Does it count as X writes, were X is the amount of "FirestoreProperty" properties the object has (assumption: "Set" is called multiple times internally)
• Something entirely different

Hi @Nyankoo,

Regardless of the number of fields being written in one operation, it still counts as one write. You may also refer to this video talking about Cloud Firestore's pricing for more information.

I'll be closing this for now. Feel free to reopen if you have any other questions.
