During the past few decades, the relational database (RDBMS) SQL has been the primary model for database management. As an alternative model for database management, the non-relational "NoSQL" databases first used in 1998 by Carlo Strozzi has been gaining steam...

You can use firebase.database().ref().limitToFirst(10)

No doubt, NoSQL databases offer many benefits to developers, but I don't think it is only Firebase that confers this real-time database. In actuality, there are many Firebase alternatives like these https://blog.back4app.com/best-firebase-alternatives/ that come with NoSQL database functionality. Likewise, open-source development platform Hasura provides support for both SQL and NoSQL databases.

Similarly, as a Firebase alternative, Back4App is also known because of its NoSQL database support. This cross-platform BaaS vendor doesn't only help to build web applications, but it is also easy to create mobile applications with it. In this regard, it provides complete support for React Native, JS, Node.js and Flutter. In the same token, Couchbase also comes with a pure cloud-based NoSQL database, just like the Firebase.
