Description: Query execution metrics are data that provide information about the performance and resource usage of a query execution in database systems. These metrics are essential for understanding how queries behave in terms of response time, CPU usage, memory, and other system resources. In the context of relational databases and distributed database systems, these metrics allow administrators and developers to identify bottlenecks, optimize performance, and improve query efficiency. Metrics may include total execution time, number of rows processed, index usage, and network latency, among others. By analyzing these metrics, users can make informed decisions about how to adjust their queries or system configuration for optimal performance. In summary, query execution metrics are essential tools for database management and optimization, providing a clear view of the performance and efficiency of query operations.
