![]() Query Statistics provide instant statistics on SQL executed from the Workbench Editor, such as details about the fields in your result set and key performance statistics from your query, such as client timing, network latency, server execution timing, index usage, number of rows scanned, joins, use of temporary data storage, and more. This allows the optimizer to create more consistent query plans over time. By showing developers costs and tuning hints, MySQL Workbench improves and simplifies SQL statement performance tuning. MySQL Workbench MySQL Enterprise Monitor SQL (DML) maintenance statements. MySQLWorkbench Visualize Explain plans graphically show and highlight how SQL statements execute within MySQL. This information can help optimize SQL performance. The explain plan shows the operations MySQL performs when it runs SQL statements. MySQL Workbench leverages the SYS views on the Performance Schema. With the tool, you can detect slow running queries, examine the workload, and analyze bottlenecks to resolve performance issues in MySQL databases. This can result in EXPLAIN statements showing different plans. Targeted reports make analyzing IO hotspots, high cost SQL statements, Wait statistics, InnoDB engine metrics. Query Profiler is a query optimization tool that helps you profile and improve MySQL query performance, as well as track the differences in profiling results when executing the query several times. MySQL Optimizer SELECT a, b FROM t1, t2, t3 WHERE t1.a t2.b AND t2.b t3.c AND t2.d > 20 AND t2. MariaDB implements some changes in the SQL query optimizer over whats available in MySQL. MySQL Performance Schema MySQL Enterprise Monitor MySQL Workbench. Over 20 reports help to analyze the performance of your MySQL databases. And you will come away with an understanding of how the MySQL optimizer works. Simply mouse over various graphs and visuals to get added details. The Performance Dashboard provides quick "at a glance" views of MySQL performance on key server, network, and InnoDB metrics. For developers, MySQL Workbench provides easy to understand views into optimizing queries and data access. The Performance Dashboard and reports allow DBAs to easily view overall server performance, and various reports provide views of IO hotspots, SQL statements, Network, Data Engine, and more. It uses the DBT-3 database and begins with the following. MySQL Workbench includes various tools for both DBAs and Developers related to viewing and improving performance. This tutorial describes how to use Explain reports to locate and fix problematic (slow) queries.
