Description: Query statistics are data collected about the performance of SQL queries, including metrics such as execution time, resource usage, and execution frequency. These statistics are fundamental for database administrators and developers, as they allow for the identification of performance bottlenecks and the optimization of queries to enhance the overall efficiency of database systems. By analyzing these metrics, informed decisions can be made regarding query restructuring, index creation, or database architecture modification. Query statistics also help to anticipate query behavior under different workloads, which is essential for application maintenance and scalability. In summary, these statistics are a key tool to ensure that databases operate optimally and that the applications relying on them provide satisfactory performance to end users.
