"queries" in MySQL refers to the number of query statements, which represents the number or statistics of queries executed within a certain period of time. By observing and analyzing the value of "queries", you can understand the performance of the database Information such as load conditions, query frequency, and whether there are potential performance bottlenecks.

In MySQL, "queries" refers to the number of query statements. It represents the number or statistics of queries executed within a certain period of time.
MySQL database maintains an internal counter to record the number of query statements that have been executed. This counter can be used to monitor database usage and performance optimization. By observing and analyzing the value of "queries", you can understand the database load, query frequency, and whether there are potential performance bottlenecks and other information.
Generally, a higher "queries" value may mean that the database is under high load, and performance optimization or additional hardware resources may be required to improve the database's processing capabilities. At the same time, for developers, "queries" is also one of the important indicators for evaluating query efficiency and optimizing database operations.
It should be noted that in MySQL, the count of queries is based on the connection. When each client connects to the MySQL server, there will be an independent "queries" counter, which records the number of queries performed by the connection. Therefore, during monitoring and analysis, the "queries" values of different connections need to be reasonably aggregated and interpreted.
