How to handle Firestore max document size?

Question

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?

You had initially tagged this with Google Cloud Storage so it seems like you might be conflating two concepts of documents (like what you might see in google drive) and a firestore document (an entry in a database). It's unclear from your question as to what a user can input. Most likely, the entirety of a user's input, whatever that is, would not be stored in a single firebase document. — imjared, Aug 12 '21 at 13:54
I only use firestore and not google Cloud, sorry for the confusion — Dalon, Aug 12 '21 at 13:57
It's still not clear what kind of data you expect your users to enter and why you'd be storing all of that in a single Firestore document. If you don't think you'd be able to fit everything, you need to rethink your architecture. — imjared, Aug 12 '21 at 14:03
I postet a picture of what it looks like, hope this helps to understand my question — Dalon, Aug 12 '21 at 14:14
The question is really impossible to answer with the limited data you've given us. For example; *why* does a user "has his own document' - that's an unusual way to structure your data as most of the time, data is spread out amongst logical groupings of collections/documents. I would suggest reviewing [NoSQL Data Modeling](https://firebase.google.com/docs/) Then update the question with details and code you're attempted. Also see [Data Modeling](https://stackoverflow.com/questions/56912654/firebase-is-it-a-good-idea-to-use-dimension-fact-table-design-in-nosql/56914411#56914411) — Jay, Aug 12 '21 at 17:32

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.

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.
