What's the difference between Cloud Firestore and the Firebase Realtime Database?
(5 answers)
Closed 5 years ago.
Recently Firebase Firestore was launched. After going through the documentation, I am confused how exactly Firebase Firestore is different Firebase Realtime Database and what are the situations in which Firestore should be used over Realtime Database as Realtime Database provides almost all the functionalites which Firestore provides (Querying, Security, Offline Capabilities).
In Realtime database of Firebase, it provides only the following features
Stores data as one large JSON tree.
Simple data is very easy to store.
Complex, hierarchical data is harder to organize at scale.
But in Firestone completely different data structure has been follow.
Stores data in documents organized in collections.
Simple data is easy to store in documents, which are very similar to JSON.
Complex, hierarchical data is easier to organize at scale, using subcollections within documents.
Requires less denormalization and data flattening.

Firestore slow queries with large collections unless offline persistence disabled

I have a very simple query which is quite slow (5seconds or more) when running it on my android.
QuerySnapshot snapshot = await userTeamPointsCollection
.where('user_ref', isEqualTo: userIdRef)
.where('season_id', isEqualTo: season)
.where('match_day', isEqualTo: matchday)
.get();
The collection consists of 10 documents, so i have no idea why the query might be slow.
I have already created a composite index, there was not much improvement.
DO you have any suggestions on what i should try or why it is so slow? (Internet is not an issue...)
Best regards,
If you are aiming for fast synchronization of (frequent) relatively small write operations, consider using Firebase's Realtime Database over Cloud Firestore.
Firebase has two NoSQL databases: Cloud Firestore and the Realtime Database. Both database's offer real-time synchronization as one of their core primitives, but Realtime Database is often faster and handles small write operations more efficiently (and often cheaper), while Firestore is best if you have relatively big documents, a larger number of (50K-1M concurrent) listeners, and relatively fewer write operations.

Do firebase cloud functions involve costs for realtime db and firestore?
(1 answer)

I am using Firebase Realtime Database to store data for my app. For some server based processing, I am using Firebase Function to do a periodic operation to read the data from the Realtime Database and update it if necessary and write it back to the Realtime Database.
I wanted to ask whether does Firebase Function operation to both read and write back to Firebase Realtime Database will contribute to the Realtime Database download usage (as Realtime Database download usage is charged)?
Reading data from the Realtime Database into your Cloud Function is a charged operation.
Note that this only applies to data that you code explicitly read in your Cloud Functions code. The data that is used to trigger your Cloud Function, and is passed into your code in the snapshot, change, and context parameters, is not charged.

I am building an app related to online bookings of Barbers in my city.I am planning to use Firebase to store my data and showing realtime updates. What will be the right option i.e. Realtime Database or Firestore. As much as I read, Firestore is great but it costs the developers according to number of queries and in my case query numbers will be much higher as I am planning to show realtime update to clients for their booking status.
And I am a naive in this area so suggest which one will be easy to learn.
It's up to you in the end, so I'll just name some main points:
Realtime Database is basically one giant JSON file, while Cloud Firestore is based on collections of documents.
Both offer realtime updating.
Cloud Firestore has better ways to filter and sort data.
Cloud Firestore has more advanced ways of writing and updating information.
Realtime Database is based on a single region, while Cloud Firestore can scale to multiple regions automatically.
They have different security options.
Realtime Database charges based on bandwidth and storage, but at a higher rate. As you mentioned in your question, Cloud Firestore charges based on operations on your database (read, write, etc.)
In the end, it all depends on how you want to work in your code. For example, do you want to work with one large JSON tree, or do you want to work with separate documents? Cloud Firestore is the newer of the two, but that doesn't necessarily mean it's better in your scenario.
I had already saved all data like users or rooms contents on Firebase Database. Now I want to move all posts to Cloud Firestore for better queries.
But,
Can I take conditions from Realtime Database?
I mean all users data are in realtime database. So I want to get some informations from there, then decide whether it's accessible or not.
The security rule systems are different between Realtime Database and Firestore. There is currently no easy to way to simply copy from one to the other, or to make one recognize the other. If you're porting your data to Firestore, you'll have to write new rules by hand that functionally match the ones you were using in Realtime Database.
No, this isn't functionality that exists. You'll need to have migrated the data that the rules depend upon to Cloud Firestore first.
I'm wondering how to store this kind of data structure into Firebase
What i have learned so far from Firebase Docs was that if we want to store JSON, we could use Firebase Realtime Database. But, if we want to store Images/Video/Files, we could use Firebase Storage.
The issue is i want to store both kind of data (string, and image). Any idea how can i achieve this ?
Put your files in Cloud Storage for Firebase, then store a URL or path to the file in Realtime Database. It's strongly recommended not to store large amounts of binary data in Realtime Database - that's simply not what it's good for.
