- Using views instead of tables Instead of traversing from table to table to get your data, expose views where the joins have been made for you. Provided that you’ve correctly indexed your tables, this approach should be very fast, and it will be even faster if you limit the results by using a delegable function that runs on the server. Using stored procedures through a flow for performance The biggest performance improvement that you can make for a PowerApps app that uses Microsoft SQL Server is to call stored procedures from an implementation of Microsoft Flow (that is, a flow). This approach has the added benefit of decoupling your database design from the PowerApps app. Therefore, you can change the underlying table structure without affecting your app. As we’ll explain later, this approach is also more secure. To use this approach in a PowerApps app that already uses the SQL Server connector, you must first completely remove the SQL Server connector from the app. Then create a new SQL Server connector that uses a SQL sign-in that’s restricted to EXECUTE permissions on stored procedures in the database. Finally, in the flow, call the stored procedure, and pass in the parameters from the PowerApps app. For a detailed explanation of how to create the flow and return its results to PowerApps, see Brian Dang’s article, Return an array from a SQL Stored Procedure to PowerApps (Split Method). This approach has these performance benefits: • The stored procedure will be optimized through a query execution plan. Therefore, data will be returned faster. • Delegable calls become less of an issue, because your stored procedure will be optimized to read or write only pertinent data. • Your optimized flow is now a reusable component. Therefore, it’s available to other makers in the environment for common read and write scenarios. https://pahandsonlab.blob.core.windows.net/documents/PowerApps%20canvas%20app%20coding%20standards%20and%20guidelines.pdf
