Peek stage

The Peek stage lets you print record column values either to the job log or to a separate output link as the stage copies records from its input data set to one or more output data sets.

The Peek stage is a development and debug stage. It can have a single input link and any number of output links.

Like the Head stage (Head stage) and the Tail stage (Sample stage), the Peek stage can be helpful for monitoring the progress of your application or to diagnose a bug in your application.

The stage editor has three tabs:

• Stage tab. This is always present and is used to specify general information about the stage.
• Input tab. This is where you specify the details about the single input set from which you are selecting records.
• Output tab. This is where you specify details about the processed data being output from the stage.
