SHOW SESSIONSGraph

登录 NebulaGraph 数据库时，会创建对应会话，用户可以查询会话信息。

注意事项Graph

执行exit退出登录时，客户端会调用 API release，释放会话并清除会话信息。如果没有正常退出，且没有在配置文件 Graph 设置空闲会话超时时间（session_idle_timeout_secs），会话不会自动释放。对于未自动释放的会话，需要手动删除指定会话 (TODO: coding)。

SHOW SESSIONS查询所有 Graph 服务上的会话信息。

SHOW LOCAL SESSIONS从当前连接的 Graph 服务获取会话信息，不会查询其他 Graph 服务上的会话信息。

SHOW SESSION <Session_Id>查询指定 Session ID 的会话信息。

语法Graph

SHOW [LOCAL] SESSIONS;
SHOW SESSION <Session_Id>;
