SHOW QUERIESGraph

SHOW QUERIES语句可以查看当前 Session 中正在执行的查询请求信息。

Note

如果需要终止查询，请参见Graph。

注意事项Graph

  • SHOW QUERIES从本地缓存获取当前 Session 中查询的状态，几乎没有延迟。
  • SHOW ALL QUERIES从 Meta 服务获取所有 Session 中的查询信息。这些信息会根据参数session_reclaim_interval_secs定义的周期同步到 Meta 服务，因此在客户端获取到的信息可能属于上个同步周期。

语法Graph

SHOW [ALL] QUERIES;
