[算法]——归并排序(Merge Sort) 归并排序(Merge Sort)与快速排序思想类似:将待排序数据分成两部分,继续将两个子部分进行递归的归并排序;然后将已经有序的两个子部分进行合并,最终完成排序。其时间复杂度与快速排序均为O(nlogn),但是归并排序除了递归调用间接使用了辅助空间栈,还需要额外的O(n)空间进行临时存储。
在未开启sort-merge-join,task 2.0.0存在比较大的数据倾斜而导致任务失败。 场景 结果 sort merge join success (耗时31.57m) shuffle hash join failed sort消除优化场景测试 测试场景: 在多张数据表进行join的情况下,若触发sort merge join时,是否可能进行sort消除。测试用例: 1000G数据集tpcds,iceberg表。 批...
As shown in the image below, the merge sort algorithm recursively divides the array into halves until we reach the base case of array with 1 element. After that, the merge function picks up the sorted sub-arrays and merges them to gradually sort the entire array. ...

In the developments, we can find some particular modifications for selected data, improved procedures to avoid deadlocks, and new structures that made it possible to increase the speed of sorting. Quick sort is composed using divisions of the data stack, in which each part is processed to ...
sort string 否 排序方式,默认值为 desc desc:降序 asc:升序 desc filter string 否 该字段主要用于过滤新旧版本的合并请求,默认不过滤,同时获取新旧版本的内容,若是一直使用新版合并请求,可忽略该参数。可选值: new:仅查询新版合并请求 old:仅查询旧版合并请求 new labelIds string 否 类标ID 列表,多个 ID...
You can see that after the first data page worth of rows, the rest of the inserts are minimally logged. The same can be done if the target table was a HEAP but in this case, you will need to use TABLOCK hint as shown here
