Spanner, Firestore, and Bigtable: Connecting the Dots (Cloud Next '19)

One of Google Cloud Platform's competitive advantages is the strong ecosystem of managed databases. However, the wealth of options can be confusing to navigate as you look for the right technologies to grow your product. Streak uses each of these technologies to build its workflow tool. Along the way to building the largest Cloud Spanner database, Streak's engineers have learned what works and what doesn't when building a production-ready system. This session will focus on picking the right databases for your tech stack and how to make it all work in a unified way.

I'm only 6 mins in at this point. She's talking about Datastore. Do they eventually switch over to talking in terms of the current proposition, Firestore? (Or maybe their team switched away from using it before the current Firestore product, and they don't bother to cover the stuff they haven't used?)

UPDATE, from after watching:
Essentially the latter: the provided evaluations on what is suitable for what are made based on the old Datastore's capabilities, not with it's successor product, Firestore's capabilities factored in.
