基于doris实时数仓实时报表生成

--创建存储过程
CREATE PROCEDURE insetAutoInsert10sProcedure()
BEGIN
INSERT INTO auto_insert_10s(id,create_time,update_time) VALUES (1,NOW(),NOW());
END
;

--创建事件定时器
CREATE EVENT IF NOT EXISTS eventAutoInsert10s
ON SCHEDULE EVERY 10 SECOND
ON COMPLETION PRESERVE
DO CALL insetAutoInsert10sProcedure();

--开始事件
alter event eventAutoInsert10s on completion preserve enable;


--定时删除表中数据
CREATE PROCEDURE deleteAutoInsert10sProcedure()
BEGIN
delete from auto_insert_10s where create_time <= now();
END
;

CREATE EVENT IF NOT EXISTS eventDeleteAutoInsert10s
ON SCHEDULE EVERY 3600 SECOND
ON COMPLETION PRESERVE
DO CALL deleteAutoInsert10sProcedure();

alter event eventDeleteAutoInsert10s on completion preserve enable;


--启动定时器
SET GLOBAL event_scheduler = 1; 

--查看存储状态
SHOW PROCEDURE STATUS LIKE '%deleteAutoInsert10sProcedure%'$$

--查看事件
SHOW EVENTS;

--删除事件
DROP EVENT eventAutoInsert10s;

--停止定时器
SET GLOBAL event_scheduler = 0; 

--删除存储过程
DROP PROCEDURE insetAutoInsert10sProcedure;

--关闭事件
alter event eventAutoInsert10s on completion preserve disable;

ps1.可根据数据查询频率指定mysql定时器频率
ps2.需要全局启动定时器，才可以创建定时任务

jdbc_StarRocks_agg flink udtf函数，传入查询sql
