二.SORT MERGE JOIN:排序合并连接 Merge Join 是先将关联表的关联列各自做排序,然后从各自的排序表中抽取数据,到另一个排序表中做匹配。 因为merge join需要做更多的排序,所以消耗的资源更多。 通常来讲,能够使用merge join的地方,hash join都可以发挥更好的性能,即散列连接的效果都比排序合并连接要好。然而如果...

Dropsort was first proposed as an alternative sorting algorithm by David Morgan in 2006, it makes one pass and is lossy. The algorithm was reinvented in 2018 as Stalin sort. The concept of dropping hash entries in a non-lossy manner was independently developed by Marshall Lochbaum in 2018 and...
