Plan Visualization for MySQL
Copyright © 2024 PawSQL
Overview
The execution plan is an internal execution strategy generated by the database when executing SQL queries. It describes how the SQL is executed step-by-step internally in the database and is an important basis for diagnosing SQL performance issues and tuning. As the complexity of database applications increases, SQL execution plans become more and more complicated along with the SQL. Relying on plaintext execution plans makes it very challenging to grasp the overall execution plan, locate key paths and bottlenecks, bringing great difficulties to DBAs' performance tuning work.
The visual execution plan tool intuitively presents the execution plan in a flowchart, clearly showing the plan structure. It uses visual elements to highlight key operations and paths, while associating SQL statement source code for integrated analysis. This can greatly improve the efficiency for DBAs to understand and analyze execution plans, quickly locate performance bottlenecks, and perform precise optimization on SQL or indexes.
