Realtime Database is a mature product and you can expect the stability from a battle-tested, tried-and-true product.

Operations can be batched and completed atomically while transactions will repeat automatically until they’re completed. Data can be written as an individual operation while transactions in the native SDKs require a completion callback.Ĭloud Firestore facilitates atomic write and transaction operations. Realtime Database facilitates basic write and transaction operations. The default query type is indexed wherein query performance is proportional to the size of your result set, not your data set. You don’t have to write deep queries instead of an entire collection or entire document, you can query subcollections within a document. Unlike Realtime Database, Cloud Firestore allows chaining the filters and combining filter and sort on a property in a single query. By default, queries are deep which always return the entire subtree.Ĭloud Firestore support indexed queries with compound sorting and filtering. In a single query, you can either sort or filter, not both, on a property. Realtime Database supports deep queries with limited sorting and filtering functionality.

Realtime Database offers offline support for mobile clients on iOS and Android only whereas Cloud Firestore provides offline support for iOS, Android, and web clients.ĭata can be retrieved, sorted, and filtered from any of the databases through queries. Cloud Firestore requires less denormalization and data flattening.īoth Realtime Database and Cloud Firestore have mobile-first, realtime SDKs and support local data storage for offline-ready apps. Complex, hierarchical data is conveniently organized at scale using subcollections within documents. Simple data is stored in documents, which is easy and similar to the way data is stored in JSON. Realtime Database stores data as one large JSON tree which makes it easier to store simple data but harder to organize complex, hierarchical data at scale.Ĭloud Firestore stores data in documents arranged in collections.

Realtime Database and Cloud Firestore, both are NoSQL Databases. Which database is a right choice for your mobile app?īefore choosing the one to go with, consider the following differences between Realtime Database and Cloud Firestore. Cloud Firestore is richer, faster, and more scalable than the Realtime Database. It is a successor to the Realtime Database with a new and more intuitive data model. For the mobile apps requiring synced states across clients in realtime, it is an efficient and low-latency solution.Ĭloud Firestore is Firebase’s newest flagship database for mobile apps. Realtime Database is the Firebase’s first and original cloud-based database. “codes screengrab” by Markus Spiske on Unsplashįirebase from Google offers two types of cloud-based client-accessible database solutions for mobile apps that support realtime data syncing - Realtime Database and Cloud Firestore.
