处理从Firebase获取的文档快照的数据是否算读？

Question

This question is regarding the billing of Firebase.

Does processing the data of a document snapshot obtained from Firebase count as a read?

So does the below code incur costs on my Billing plan and thus counts as a read or is it just post-processing the already obtained data or snapshot?

docSnapshot.data().toString().contains('hello')

Question: So does the below code incur costs on my Billing plan and thus counts as a read or is it just post-processing the already obtained data or snapshot?

Answer: It is "just post-processing the already obtained data or snapshot". You pay one read when you fetch the document from Firestore to your client.
