The SQL Explorer and Audit feature incorporates the SQL statement search and SQL Explorer features based on the full request analysis and security audit capabilities of Database Autonomy Service (DAS). You can query information about executed SQL statements and use the information to troubleshoot performance issues and identify risk sources. In addition, you can use the traffic playback and stress testing feature to check whether you need to scale up your database instance to handle workloads during peak hours.
