   ### Description
   
   When small batches of data are merged into a target table with a large 
amount of data, the speed will be very slow. Instead, using the following steps 
will significantly improve speed:
   1. Create a temporary table
   2. Insert data into the temporary table
   3. Merge the data from the temporary table to the target table
   4. Delete or clear the temporary table
