I have a project with a firebase database and it works fine tell now.
Should I migrate my firebase database to firestore database?
Are advantages deserve the effort to build a new database because up to my knowledge there is no available way to migrate the database automatically tell now.
Firestore is currently in beta (meaning its API could change under your feet), so I would recommend against migrating until it is full-fledged.
Furthermore, there is a difference when it comes to pricing. In Firestore, you're charged for read/write/delete + storage. In Firebase, you are only charged for storage.
You can find a more detailed breakdown here.

I'm using sqlite to store data in my app, i would like to sync my database with firebase so that i can do modify data from firebase and insert it into my database without updating the app. Any suggestions how can i do that.
You don't need to sync Firebase with your local database. Firebase provides you SDK to perform read/write operations in your database. You might only need to update your application if there is a schema change. That too can be achieved without keeping the computation logic in the Cloud and instead call Cloud Functions for cases where you know there are going to be a lot of schema changes.
Firebase provides you really well documented APIs and code samples. You can refer the following links for more information:
Firebase Docs -- SDKs here
Cloud Functions -- For cloud computation
Realtime Database -- Database for realtime transfer, can be costly for high usage. Generally used for PoC or low traffic projects
Firestore -- Upgraded version of Realtime DB. Generally used for high traffic.
I am looking for a solution for developing iOS and Android chat to replace our current (unreliable, maybe poorly written by previous devs) XMPP/OpenFire chat. I came across Firebase which looks good. However, I don't quite get the setup for it.
Can I host Firebase on my own server and not have to subscribe to any of Firebase's plans?
Firebase offers a few products:
the Firebase realtime database
Firebase hosting (for hosting static resources)
Firebase authentication
I think you are looking for the Firebase realtime database.
There is no way currently to host the Firebase realtime database on your own servers.
Probably to late to be of any help but an alternative is RethinkDb. It is an open source realtime database and can be installed on your own machines.
Never used it myself just researching my options like you.
One more tool to add to the list is Appwrite. It is a self-hosting solution that seems to be inspired by firebase. It has much if not all of firebase's functionality. PS: I am not in any way associated with the project, just a (happy) user.
You should check if RESTHeart fits your needs. It's mainly a REST, GraphQL, and WebSocket API on top of MongoDB, but it has many additional features
The Open Source Firebase Alternative supabase
currently it supports Postgres realtime Database, Authentication and storage only .
And it can be installed on your own server supabase self hosting docs

What's the difference between Cloud Firestore and the Firebase Realtime Database?
(5 answers)
Closed 5 years ago.
On the firebase console a Cloud Firestore tab has been added and going through the documentation it has some similar features like Realtime database. My android app already uses the Real-time database, functions, and storage and everything work fine. I would like to know how the Cloud Firestore can make my application better and what are the special features present only in Firestore that are not there in the real-time database that could improve my application.
I have a chat based application running on the real-time database and I am performing very frequent requests for small amount of data. Will switching to Firestore reduce my cost? Will it maintain or increases the speed of operation?
A developer advocate answers in blog post
The main points:
Better querying and more structured data
Designed to Scale
Easier manual fetching of data
Multi-Region support for better reliability
Different pricing model
The Cloud Firestore is an upgrade on the Real-time database although the Cloud Firestore is still in beta.
The Cloud Firestore offers
Better and faster data queries. With the C. Firestore, data at the top collections can be fetched without grabbing any sub-collections in its children node. This prevents downloading unwanted data from your db unlike the real-time db.
Scalability: The above already explain why this is more scalable.No matter how large your db is, your app will only request for necessary data unlike the real-time db.

I have been using SQLite as my storage solution for my android applications. I want to be able add synchronization functionality to one of my apps, Firebase looks like a good solution but the problem is that I need to know if I am to use Firebase to sync data with the SQLite database or Firebase can work and totally replace SQLite. I know Firebase has offline persistence but while offline can it hold as much data as SQLite and are the queries as powerful?
Clearly this depends on the business rules for which the options are considered. So there will not be the "right" answer to this.
At least one of our team members was thinking along these lines. Here is our solution:
Do all transactional data locally on the SQLite as we do not need transactions to be across devices.
Sync the rest using Firebase.
(1) makes sure that we don't misuse Firebase's non-persistent offline availability of its client.
The docs
Even with persistence enabled, transactions are not persisted across app restarts. So you cannot rely on transactions done offline being committed to your Firebase Realtime Database. To provide the best user experience, your app should show that a transaction has not been saved into your Firebase Realtime Database yet, or make sure your app remembers them manually and executes them again after an app restart.
(2) make sure that we use Firebase's persistent offline nature to synch non-transactional data across devices once connection is (re)established.
The docs, The Firebase Realtime Database client automatically keeps a queue of all write operations that are performed while your app is offline. When persistence is enabled, this queue is also persisted to disk so all of your writes are available when the user or operating system restarts the app. When the app regains connectivity, all of the operations are sent to the Firebase Realtime Database server.
This way we achieve a state acceptable within our use.
"can it hold as much data as SQLite and are the queries as powerful?" no and no if powerful is translated as "transaction across devices", by definition of Firebase being a remote database.
In my first version of android app I have used SQLite database. Now I want to convert everything to Firebase real time database. I don't want to use SQLite database anymore because of offline capabilities of firebase. Since previous version of app has a number of user and everyone has their own data stored, I don't want, user lose data while upgrading app. How I migrate previous version SQLite database to new version Firebase real time database?
