How to Roll Out a Database Change Across Multiple Application Regions

Applications in different regions may not deploy at the same time. A schema change can break older application instances or replicas if it reaches one region before others are compatible.

What to check

Map regional versions, replication topology, migration ordering, read and write traffic, and rollback constraints. Test mixed-version behavior and monitor replication lag during staging.

Recommended next step

Use backward-compatible phases and coordinate rollout by region with explicit health gates. Confirm every region and background worker uses a compatible schema before removing old fields.
