Reliability and performance

When we choose the database for our project, then reliability and performance are the most important parts that come to our mind:

Realtime Database	Cloud Firestore
Realtime Database is a mature product: Stability you'd expect from a battle-tested, tried-and-true product. Very low latency, so it's a great option for frequent state-syncing. Databases are limited to zonal availability in a single region.	Cloud Firestore is currently in beta: Stability in a beta product is not always the same as that of a fully launched product. Houses your data across multiple data centers in distinct regions, ensuring global scalability, and strong reliability. When Cloud Firestore graduates from beta, it will have stronger reliability than Realtime Database.
