a) Cloud Firestore supports transactions across the entire database. You can learn more about them here: https://cloud.google.com/firestore/docs/manage-data/transact....

b) Given that the primary use case for namespaces was/is multitenancy, it's not clear to me why you'd want to transact across them. Nevertheless, you can. What's leading you to draw this conclusion?

The documentation is what led me to that conclusion, since it's not explicit as to what the transaction boundaries are, but I could be mistaken. Does this mean that the poster's claim is erroneous?

[itcmcgrath]

It does. It's not in the documentation because it doesn't have boundaries within the database.

Can you have more than one database per project? If so, there still might be a valid claim here.
