You use ASP.NET Core MVC with ADO.NET to develop an application. You implement database sharding for the application by using Azure SQL Database. You establish communication links between the shard databases.
You need to implement a strategy that allows a group of operations that are performed on multiple Azure databases to be rolled back on all databases if any of the operations fail.
Solution:
-> Create stored procedures in each Azure SQL database instance to perform operations for each respective database.
-> Invoke a named transaction in each stored procedure.
-> Establish a new transaction scope in a using block. Within the block, establish connections to each Azure SQL Databases instance and run the stored procedure.
-> If no exception occurs, commit the scoped transaction.
