How to handle Firestore max document size? - firebase

According to Firestore, the max document size is 1MiB. In my app, every user has his own document. So can every user have a maximum storage size from 1 MiB or do I understand this wrong?
Because in my app the user can input a lot of data, so I fear that the Storage is not enough. How to handle this problem?

So can every user have a maximum storage size from 1MiB or do I understand this wrong?
Yes, that's correct. You are limited to 1 MiB for each document.
Because in my App the user can input a lot of data, so I fear that the Storage is not enough
If you are afraid of reaching the limit, then you should consider storing the data in other collections as well. In your case, I would create a collection of "plans" as well as one of "todos". In this way, you aren't limited in the number of documents you can add to a collection.
How to handle this problem?
For Android, there is a library called FirestoreDocument-Android, which will help you check against the maximum of 1 MiB (1,048,576 bytes) quota.

Firebase Error: Document Exceeds 1MB size limit. How to work around it?

I'm having this problem when trying to register a user on the database. The database template is a document specific to the registered user in which it has 3 arrays of objects.
I searched on the internet a little bit about it, and people seemed to say that creating a subcollection would solve it, but I don't get how it would solve the problem nor avoid it happening again in the future when theses arrays grow bigger since the subcollections are also limited by 1MB of size limit, or even needing to make multiple fetchs instead of only one if I understood it correctly.
I believed firestore was a database. Isn't it one? How can't I store data in a database then, being so limited? What's the logic behind Firestore for doing that?
And if so, how do I get around it so it never happens again?
The size limit of 1MB applies to each individual document. Subcollections are not part of it.

Does 1 mb size limit apply to a sub collection in inside a document in Firestore?
Does the size of subcollections included while calculating the document size and add to the limit of 1MB?

what is the maximum size of a document in Realtime database in firestore

I am working on a more complicated database where I a want to store lots of data, the issue with fire store is the limit to 1MB per documents, and I am splitting my data in to different document but still according to my calculation the size will be bigger than the limit, yet I cannot find the limit for the Realtime database, and I want to be sure before switching to it, my single document in some cases could hit 6-9mb when scaling big.... at first I want to go with mongodb but I wanted to try the google cloud services.. any idea if the do size is same for both Realtime and firestore ?
Documents are part of Firestore (that have 1 MB max size limit each) while Realtime Database on the other hand is just a large JSON like thing. You can find limits of Realtime database in the documentation.
Property
Limit
Description
Maximum depth of child nodes
32
Each path in your data tree must be less than 32 levels deep.
Length of a key
768 Bytes
Keys are UTF-8 encoded and can't contain new lines or any of the following characters: . $ # [ ] / or any ASCII control characters (0x00 - 0x1F and 0x7F)
Maximum size of a string
10 MB
Data is UTF-8 encoded
There isn't a limit of number of child nodes you can have but just keep the max depth in mind. Also it might be best if you could share a sample of what currently takes over 6 MB in Firestore and maybe restructure the database.

Monitor stored data size in Firestore

Firestore costs are based on document operations and on size of stored data.
In the Firebase console, we can easily track number of document operations but I don't find any place where I can track size of stored data.
I have only found in Google Cloud Console (in App Engine > Quotas) a metric corresponding to the amount of stored data in gigabyte stored the current day, but not the total amount of stored data.
Is there a means of monitoring total size of stored data (ideally with indexes included) ?
It seems that the only available option at this moment is to calculate the storage size for Cloud Firestore in Native mode manually.
I have submitted a feature request asking to implement a solution that would display the size. I'd recommend you to star that request to be notified once there is an update in the thread.

is there a limitation for query a collection in Firebase Firestore?

I have watched videos about Firestore on YouTube. It is said that there is a limitation for a where which the max size is 1 Mb and also maximum 1 write per second.
How about the query to a collection? Is there a limitation for this? Because I will heavily rely on a parent collections to perform different queries for a lot of users. That's why I need to know the worst case scenario. I need to know if there are any limitations.
I mean something like, maximum number of query per second, max concurrent queries? Maximum number to get data from a collection in a second ? Do such limitations exis for querying a collection?
I have tried to read the documentation from here and it seems there is no limitation for query in a collection. I need to make sure, maybe there is documentation that I have not read yet?
There is no documented limit to the number of queries you can execute against Firestore. While there is probably a physical limit, you're extremely unlikely to hit it before running into any of the documented limits (such as the 1 million concurrent users).
In other words: it is quite unlikely you'll need to worry about the read scalability or limitations of Firestore for your application. It is made to scale very well on read operations, which is precisely the reasons why it supports a more limited set of functionality, and why it has a write throughput limit on individual documents.
Firestore scales massively for read operations. When using the Blaze payment plan, there are no fundamental read limits like there are for write limits. You just need to be willing to pay for all those documents reads, and the bandwidth required for all that data. Please read the pricing page about billing.
There is limit for Your reads and writes.
They have provided in their document where in Free service you have limited read writes.
Each read will be counted in normal queries it acts same with writing document

Limitation to number of documents under one Collection in firebase firestore

I am new to firebase firestore and searched, but could not find the limitation for the number of documents that can be handled under one collection. Can anybody help me out to know please.

There is no documented limit to the number of documents that can be stored in a Cloud Firestore collection. The system is designed to scale to huge data sets.
There is no limitation on the number of documents in Firestore collection but it has a limitation of the size of the document.
The maximum size of a document is roughly 1 MiB (1,048,576 bytes).
There are many more limits that are listed in the below link.
Limits of firestore
There is no document limit under one collection
Official documentation for clearness: Click here
But there is limitation in maximum depth of subcollections
there is no limits in documents as #Frank saids, however to answer the question from #Tri, there is a limit of number of sub collections (100) that means collection inside collection
