 > Unlike in MySQL, the `max_execution_time` system variable currently works on all kinds of statements in TiDB, not only restricted to the `SELECT` statement. The precision of the timeout value is roughly 100ms. This means the statement might not be terminated in accurate milliseconds as you specify.
 
+### `interactive_timeout`

+- Scope: SESSION | GLOBAL
+- Default value: 28800
+- This variable represents the idle timeout of the interactive user session, which is measured in seconds. Interactive user session refers to the session established by  calling [`mysql_real_connect()`](https://dev.mysql.com/doc/c-api/5.7/en/mysql-real-connect.html) API using the `CLIENT_INTERACTIVE` option (for example, MySQL shell client). This variable is fully compatible with MySQL.
