# Top Sql Features
+ Visualize the top 5 class SQL statements with the most CPU overhead
+ Support for querying a specified TiDB Server and TiKV instance
+ Support for counting all SQL statements that are being executed
+ Supports detailed execution information such as number of request per second, average delay, query plan, etc.

Features:

- Visualize the top 5 class SQL statements with the most CPU overhead

- Support for querying specified TiDB Server and TiKV instances

- Support for counting all SQL statements that are being executed

- Supports detailed execution information such as number of request per second, average delay, query plans, etc.

Scenarios:

- The monitoring graph shows that the CPU of individual TiKV instances in the cluster is very high. I hope to understand which SQL statements the CPU hot spots come from in order to optimize them and make better use of distributed resources.

- The overall CPU usage of the cluster is very high and database queries are slow. Expect to quickly know which SQL statements are currently overhead the most CPU resources in order to optimize them.

- The overall CPU utilization of the cluster has suddenly changed significantly, and I would like to understand the main SQL resource overhead differences before and after the change.

- Analyze the status of the SQL statements currently consuming the most resources in the cluster and hope to optimize them to reduce hardware costs.
