Sample stage Pecent Option
Posted: Fri Dec 24, 2010 4:06 am
I am clear on sample stage period method
But confused with sample stage Percent option
What i understand is it gives you X pecentage of records to output based on a seed value(Random Genrator).
I have job => SqFile->Sample Stage->SqFile(I am using a two node file)
I have 10 records in the input When i give percent as 50 and Seed value as 3 I get 3 records in out put
and when i specify percent as 70 and give seed value as 100 I get 9 records in the output .
Can any one please explain me in undestanding what actually is happening here .
