Sample merging after matching

◆ the data matching workload is very large, and sometimes it can not be completed at one time, so it may take several times to complete. Finally, these samples need to be combined.

◆ some systems operate continuously day by day and year by year, and new data will appear continuously. In order to make the data more comprehensive, if you want to add the data samples to the old data samples, you need to merge the new samples into the old samples.
