Does firestore support acid transactions?

Question

Looking into firebase for running a "serverless" app, was curious to know how much of ACID does firestore support? there documentation has some information on transactions only but nothing more.

Answer 1

Cloud Firestore supports multi-document ACID transactions. ACID in that the transactions are:

• Atomic: All or none of the document mutations are applied
• Consistent: No transaction will leave the DB in an inconsistent state
• Isolated: Strict serializability, just like Google's Cloud Spanner
• Durable: It's synchronously replicated across regions.
