Theoretically, there is no need for the Undo (rowid) of direct insert, because hwm cannot be used by other processes during the moving process, you only need to record the redo and undo of the space involved in this direct insert operation. When the rollback fails, you only need to change these spaces to the original state, instead of record them one by one. That is to say,

The previous article summarizes the direct selection sorting and heap sorting, which summarizes the direct insertion sort and the hill sort in the insert sort, which we summarize mainly from the following points.1. Direct insertion sequencing and algorithm implementation2. Hill Sorting and algorithm implementation3. Direct
