Azure SQL Database Index Advisor helps you improve the performance of your databases by providing index recommendations based on your historical database usage. As your application and database workload evolve over time, recommendations from Index Advisor adapt and evolve as well.
Index Advisor makes it easy to implement and validate recommended tuning actions. You can choose to review and apply recommended actions yourself or have the service implement recommended actions automatically as they are published.
