A complete DBA workflow for troubleshooting T-SQL query performance degradation on Amazon RDS for SQL Server using three integrated tools. CloudWatch Database Insights detects high CPU and identifies top resource-consuming queries. Query Store then diagnoses execution plan regressions, revealing when the optimizer switched from an efficient Index Seek to a costly Index Scan.
