Cloud Firestore vs Realtime: How To Choose The Best Database For Your Mobile App?

Firebase is a NoSQL cloud service, supplied as a part of the Google Cloud Platform database offerings. It is primarily based on a file version and may be used to save and sync statistics in real-time with horizontal scaling. You can use Firebase for multi-consumer packages, consisting of mobile apps, serverless packages, and offline packages. Firebase consists of functions for authentication, crash reporting, messaging, overall performance monitoring, and analytics. Firebase is available through SDK and API, with assistance for each Unity and C++. You can combine it with a huge form of offerings and utilities, together with Kubernetes deployments, BigQuery, Google Marketing Platform, Data Studio, JIRA, and Slack.

Cloud firestore vs realtime

Cloud firestore

Cloud Firestore is a more recent database model that makes use of collections of files to save statistics. This shape permits you to save statistics just like tables and rows, increasing the database’s compatibility. Available sorts encompass booleans, gadgets, arrays, numbers, strings, and null values. You additionally have to get admission to geopoints, timestamps, and shallow references to files. These sorts permit you to manipulate statistics integrity and hunt type-primarily based totally insects greater effortlessly.

Realtime database

Realtime Database is a database that makes use of JSON files to save key-price pairs. It consists of functions for statistics synchronization the use of web sockets and asynchronous syncing for offline tool assistance. The database SDK gives assistance for the web, Android, and iOS packages.

When the use of Realtime Database is required to jot down the code at the customer you’re the use and cope with the good judgment within the customer app. Alternatively, you may use Firebase Cloud Functions to deal with requests however this impacts your capacity to apply many SDK functions.

Data structure

Realtime Database, you’re the handiest capable of saving statistics as a file tree. This makes it hard to arrange statistics, particularly at scale. Because of this, Realtime Database is satisfactory for easy statistics.

Cloud Firestore collections make it tremendously clean to save hierarchical statistics. These collections permit you to nest gadgets and require much less denormalization than real-time Databases. This makes Cloud Firestore higher perfect for complicated statistics.

Querying within the database

Realtime databases are constrained to 1 operation at a time. You can both clear out or type however no longer each in a single question. Additionally, any queries made go back your whole subtree due to the fact queries are deep through default.

In Cloud Firestore, you may carry out listed queries that permit you to carry out compound filtering and sorting. This helps you to question for subcollections. It additionally regularly method that question overall performance is higher considering the fact that it’s miles primarily based totally on end result set instead of statistics set size.


This obstacle calls you to outline guidelines for validation and authorization individually.  Additionally, your protection provision is constrained to the firebase security guidelines you create.

With Cloud Firestore, you may use each firebase security guidelines and identity and access management through server SDKs. Firebase additionally consists of automated statistics validation without cascading, even though you may put in force cascading manually. The drawback of that is that queries can also additionally fail if the customers don’t have to get admission to all outcomes statistics.

Reliability and performance

Realtime Databases are constrained to a single place of availability. This gives very low latency and is satisfactory for common state-syncing. Additionally, to scale in real-time database, you want to put in force sharding.

Cloud Firestore in more than one area with automated worldwide scalability. You have the choice to apply it domestically or multi-domestically with statistics mechanically duplicated for availability.


Firebase offers database offerings which are the cloud firestore vs realtime database. The Realtime Database makes use of JSON files to save key-price pairs, synchronize statistics through WebSockets and works for Android, iOS, and web apps. Cloud Firestore makes use of collections of files to save statistics, every file in a set can keep subcollections, and the database additionally can provide real-time updates.
