In datastage both peek and copy stages are called stub stages.
Copy stage allows us to copy the input records into multiple o/p links, includes file stages or processing stages.
peek stage is one of the debug stage, which allows us to view
the sample no of records in log or to output file, but not to
any other processing stages.
