What is cloud firestore used for?

A collection contains documents and nothing else . It can’t directly contain raw fields with values, and it can’t contain other collections. (See Hierarchical Data for an explanation of how to structure more complex data in Cloud Firestore.) The names of documents within a collection are unique.

Cloud Firestore is a NoSQL document database that lets you easily store, sync, and query data for your mobile and web apps – at global scale.

Firebase works with two different databases. The Real-Time Database is the original Firebase database product, and Cloud Firestore is a new and improved version of the Real-Time Database . Firebase offers file storage security for users and enables them to utilize Google Cloud Storage.
