Tuning an Azure SQL Database

Automatic Tuning

Azure SQL Database Automatic tuning utilizes artificial intelligence to continuously monitor and improve queries executed on an Azure SQL Database.

Automatic tuning observes the workload and applies recommendations to speed up performance. The recommendations are applied when the database activity is low so that there aren't any performance impacts when applying recommendations.

The following are the options which are available for automatic tuning.

Create Index

Automatically identify and implement missing indexes to improve workload performance. It also verifies whether or not the indexes created have any improvement on the performance.

Drop Indexes

Automatically identifies and removes duplicate, redundant, and unused indexes.

Force Last Good Plan

Automatically identifies the queries using the execution plan which are slower than the previous good plan and forces the last known good plan to improve the query's performance.
