I don’t understand well how sampling is used.

In which scene do you use the sampling? Or is it both scenes? Or is it a different scene?

A)  Perform sampling in order to obtain information on the entire DB while DB is in operation.

B)  I know roughly the process to be late. When investigating the reason for delaying the processing, sampling is performed on the processing.
