What it is
An episode of the Firebase team's 'Get to know Cloud Firestore' series, presented by Todd Kerpelman, explaining how Cloud Firestore bills for document reads, writes and deletes, storage and bandwidth. It compares this model with the Realtime Database and gives tips for keeping database costs down.

I found this video excellent to help dispel some myth and provide a great sense on how to manage cots. There is likely smart ways to set up you use case to not have significant costs unless you use case becomes extremely popular. [this video] I hope this helps a little bit!

Document reads that are satisfied from the local cache are not charged. If your local cache contains the most recent data, then most reads will be against the local cache (and thus not charged). There is a great video about Cloud Firestore pricing [this video] , that explains a lot of details.

You are going to be billed for two reads. You will find more details in this official video: [this video] , in particular at 2 min 18 sec.

Firebase might not be the best for such a heavy continuous realtime database usage. Watch this video to get some insight: [this video]
Recommends Doodles · 2019-04 · Stack Overflow · on “How do I prevent firestore from loading entire user data every time the app loads”
I would say the problem isn't even redux or firestore persistence since there is not enough information (Does it work without redux? How are you getting that data? Show us a bit of code) in the post I'll try to answer as is but you should elaborate a bit more. It is very important to note there is a BIG PROBLEM if you have 800+ reads from basically anything, nothing in any kind of app should be remotely able to generate 800 reads upfront. First of all you have to optimize this user data querying and probably the firebase structure for the data, for that I recommend watching this video [this video] from the official Firebase YouTube channel and reading this article [LINK] in the Firebase documenta

You won't be charge for 10 000 reads but only the documents retrieved by your query, ten in your example. Here's a good video from Firebase explaining their billing system : [this video] Also keep in mind that for queries other than document reads, such as a request for a list of collection IDs, you are billed for one document read.

@jbxbergdev you can always test it. Just create testing project write a code and run it once. In Firebase console in Firestore you will see reads in "Usage". Please as well watch the video from the documentation ( [this video] ) I am not sure what more to add.

That is the expected and documented behavior. This part of the pricing model is based on document reads, so you're charged per document that you read. If you want to be charged fewer document reads, the solution is to read fewer documents, for example by implementing pagination [LINK] . If you're new to Firestore, I recommend checking out the excellent video series Get to know Cloud Firestore [LINK] . For this topic, there is an entire episode on Firestore pricing [this video] .

You will only be charge for the amount of documents that you receive back from the query. Assuming you perform `const ids = admin.firestore().collection("devices").where(...).get();` and get back 1000 user ids then you will be charge for 1000 reads. Additionally, in the users collection, if you would perform a search for each user id received, then you would perform another 1000 reads. In total, you would perform 2000 reads.

Cites Agung · 2019-12 · Stack Overflow · on “will I be charged if I evaluate value using resource.data in firestore security rules?”
from the video about firestore pricing here: [this video] it is said that if I use get() or exist() in security rules, I will be charged for one read. how about evaluating a field of existing document using resource.data ? for example if I evaluating 4 fields from one documents like this: function isValidUserUpdate() { // to restrict, certain user fields can't be updated return incomingData().banned == existingData().banned && incomingData().uid == existingData().uid && incomingData().premiumUser == existingData().premiumUser && incomingData().verified == existingData().verified } function existingData() { // Data that exists on the Firestore document return resource.data; } function incomingData
