I wonder how they ensure durability. Is it possible that a cell going down would roll back a payment after it has occurred. Or do they depend on a non cell database?

I would assume nothing related to a given transaction crosses the cell boundary.

We use a cellular architecture to help constrain the blast radius of a modular monolith. Each one of our customers lives in exactly 1 cell. Any kind of cross-customer BI/reporting happens through a data warehouse.
