Firebase 是否仅针对更新 Cloud Firestore 中的字段向您收费？

Question

Base on the Firebase Billing system they are only charging for read, writes and deletes in Cloud Firestore. Do they charge for just updating a field in a document in Firestore?

Answer 1

According to this documentation :

Charges for writes and deletes are straightforward. For writes, each set or update operation counts as a single write.

Just to add, if you're update or set has failed then you're not charged as there's not any document change.
