What is Cloud Firestore? Android Studio


Cloud Firestore like Firebase Realtime Database, keeps data in-sync across client apps through realtime listeners and offers offline support for mobile and web so you can build responsive apps that work regardless of network latency or internet connectivity.

Cloud Firestore is a flexible, scalable database for mobile, web, and server development from Firebase and Google Cloud Platform.

How Cloud Firestore works?

Cloud Firestore is a cloud-hosted, NoSQL database that your Android and web apps can access directly via native SDKs.

Following Cloud Firestore’s NoSQL data modal, you store data in documents that contain field mapping to values.

Documents are stored in collections.

NoSQL database means that we don’t use tables and columns and rows instead when we create a Firestore database we split our data into collections and inside these collections, we store documents that you can think of records.

One of the great things about using Cloud Firestore is that it takes a lot of the work of our hands to make stunning data for web, and Android apps very simple to do.

In Firebase Realtime Database you have to perform all write operations in just one single query or single thread in kind of situation, but for Firestore you can make them a batch process so that you can collect all the data which you need to write in a database and just can process them as a batch operation.

Firestore is completely managed serviced and scaled automatically by Google Firebase meaning that we don’t need to worry about anything.

Also, another thing about Firestore is that we can make all of our database queries from the front end we don’t need to worry about the server-side code, if we don’t want it we can simply just use the firebase SDK to communicate with our database no matter what from technology that we are using.


Firebase is a backend system where you can store data for your app i.e. you can store users’ messages, images, etc. Firebase is from Google.
