Microsoft added several features to SQL Server 2019 that can improve performance without changes to code. One of these is T-SQL Scalar UDF Inlining. The use of UDFs is a red flag when tuning queries, but, in some cases, the engine will treat these as if the underlining code was added directly to the select statement. Tune in to this session with Kathi Kellenberger to see when this new feature will help, and, more importantly, when it won't. [01:10] What are UDFs?[01:47] Performance Issues[02:30] UDF Scalar Inlining[03:15] Demos[11:40] Control when inling is used Resources:Scalar UDF InliningGet Your Scalar UDFs to Run Faster Without Code Changes About Kathi Kellenberger:Kathi Kellenberger is the editor of Simple Talk at Redgate and a Data Platform MVP.

Jimmy Campbell is back to show Scott Hanselman how to use App Configuration for feature management. Traditionally, shipping a new application feature requires a complete redeployment of the application itself, and testing a feature often requires multiple deployments of the application. Now you can use feature flags in App Configuration to grant early access to new app functionality in production.[0:00:00]- Introduction[0:00:24]- Episode start[0:03:47]- Demo: Simple feature flags[0:06:56]- Exploring the code[0:12:26]- Demo: Conditional processing with feature filters[0:19:35]- Episode wrap-upApp ConfigurationQuickstart: Add feature flags to an ASP.NET Core appGetting started with Azure App Configurationmicrosoft / FeatureManagement-Dotnet on GitHubFeature management overviewCreate a free account (Azure)
