We built a distributed DB capable of running across 100s of global locations

In my opinion, an edge native database is something that allows reads and writes locally in all locations in parallel and does not require a user to magically know which data should be placed in which location or require that user to redesign the schema every time they want to add/remove a location. This allows a single database system to support multiple data models against a single, integrated backend. A database or streaming system that can geofence the data natively with strong isolation and does not require schema changes when a business expands to more regions.
