原创 Hive中的map join、left semi join和sort merge bucket join

left semi joinleft semi join（左半连接）用于替代in/exists操作。--in/existsselect a.id, a.name from a where a.id in (select b.id from b);select a.id, a.name from a where exists (select id from b where a.id =b.id);--join（效果等同）select a.id, a.name from a join b on
