Isn't it actually built on top of Datastore?

  It is, that is also where the name is coming from (Firebase + Datastore = Firestore). Firestore also differs a lot from Cloud Spanner, most notably in the way that it can be used directly on the client, whereas Cloud Spanner is meant to be used in combination with a server side application.

    Firestore also has server side apis and client libraries. But yeah "same same but different".

  Long story short. It's using spanner tech under the hood. "And for you database aficionados out there, we should point out that our multi-region database offers strong consistency (just like Cloud Spanner!),"

    That's not what the quoted text really means; Datastore has a form of strong consistency too. I'm pretty sure Firestore is built on Datastore. https://cloud.google.com/datastore/docs/concepts/structuring_for_strong_consistency https://cloud.google.com/datastore/docs/concepts/structuring...
