Is there a way to detect how many columns that have come in via RCP? I have a Sequential File stage using RCP. The next stage is a Transformer stage. In the Transformer stage I want to know/detect the total number of columns coming from the Sequential File stage. Is this possible? Thanks in advance for any help.
What you are seeking to do is not possible, unless you load the count from the schema file into a job parameter to which the Transformer stage has access.
