版本2.0.2
条件：t1表40w+,t2表70w+,t2积累的数据比较多，t1是新表
explain SELECT * FROM t1 left OUTER JOIN t2 ON t1.date = t2.dt AND t1.hour = t2.hour AND t1.pchannel = t2.pchannel WHERE t1.date = '2024-10-08' AND t2.dt = '2024-10-08' and t1.media_type = '2' and t2.pchannel='xxx';
执行计划中为什么显示的inner join这个比较费解，改变了语义，这个条件中左表里有数据右表里没有数据，想要的结果是如果右表里没有数据左表的也会展示出来
