The production environments. This document describes how to use Top SQL to locate SQL queries that contribute to a high load of a TiDB or TiKV node in a specified time range. For example, you can use Top SQL TiKV node, Top SQL provides the following features: • Show the top 5 types of SQL queries that contribute the most to the load in a specified time range. • Show information such as CPU usage, requests
