Google Cloud Firestore Operators
================================

`Cloud Firestore <https://firebase.google.com/docs/firestore>`__ is a flexible, scalable database for mobile,
web, and server development from Firebase and Google Cloud. Like Firebase Realtime Database, it keeps
your data in sync across client apps through realtime listeners and offers offline support for mobile and web
so you can build responsive apps that work regardless of network latency or Internet connectivity. Cloud
Firestore also offers seamless integration with other Firebase and Google Cloud products, including
Cloud Functions.
