Goal Determine whether Cosmos DB can automatically revert writes that succeed before a schema validation rule change but become invalid after the change, without requiring application‑level compensation. The container‑level JSON schema validation is enforced at write time, and while TransactionalBatch provides atomicity across documents, a schema modificatio
Cosmos DB Native Schema Version Toggle for Deployment Rollback Azure Cosmos DB is schema-agnostic, so application deployments often write documents with new structures without a database-enforced schema version. When a deployment fails validation after those writes, the database has no native mechanism to automatically revert document structures to a previou
