Description
每个 Doris 的连接都在一个单独的线程中运行。 您可以使用 KILL processlist_id 语句终止线程。
线程进程列表标识符可以从 SHOW PROCESSLIST 输出的 Id 列查询 或者 SELECT CONNECTION_ID() 来查询当前connection id。
语法：
KILL [CONNECTION] processlist_id
除此之外，您还可以使用 processlist_id 或者 query_id 终止正在执行的查询命令
语法：
KILL QUERY processlist_id | query_id
Example
- 查看当前连接的connection id。
mysql> select connection_id();
+-----------------+
| connection_id() |
+-----------------+
| 48 |
+-----------------+
1 row in set (0.00 sec)
- 查看所有连接的connection id。
mysql> SHOW PROCESSLIST;
