What is Sample Stage?
What is Sample Stage in Development and Debug Stage ?
Sample Stage:
1.The Sample stage is a Development/Debug stage.
2. It can have a single input link and any number of output links when operationg in percent mode,
3. And a single input and single output link when operating in period mode
4.The Sample stage samples an input data set. It operates in two modes. In Percent mode, it extracts rows, selecting them by means of a random number generator, and writes a given percentage of these to each output data set. You specify the number of output data sets, the percentage written to each, and a seed value to start the random number generator. You can reproduce a given distribution by repeating the same number of outputs, the percentage, and the seed value
5.In Period mode, it extracts every Nth row from each partition, where N is the period, which you supply. In this case all rows will be output to a single data set, so the stage used in this mode can only have a single output link
6.For both modes you can specify the maximum number of rows that you want to sample from each partition.
The stage editor has three pages:
Stage Page.This is always present and is used to specify general information about the stage.
Input Page.This is where you specify details about the data set being Sampled.
Output Page. This is where you specify details about the Sampled data being output from the stage.
