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.
