Firestore rules

If you plan on using other Firebase or Google Cloud products, then Firestore is a great choice due to the close integration between products . An example of this is that Firebase Authentication already has integration with Firestore out of the box so you don’t have to worry about setting this up.

Cloud Firestore provides a programmatic interface for retrieving data based on “references,” with a SQL-like query syntax designed for asynchronous processing. MongoDB is a more robust document database known for high performance and best-in-class security , and has several advantages over Firebase.

Cloud Firestore also features richer, faster queries and scales further than the Realtime Database . Realtime Database is Firebase’s original database. It’s an efficient, low-latency solution for mobile apps that require synced states across clients in realtime.
