Lookup stage: Output tab
The Output tab allows you to specify details about data output from the Lookup stage.
The Lookup stage can have only one output link. It can also have a single reject link, where records can be sent if the lookup fails. The Output name list allows you to choose whether you are looking at details of the main output link (the stream link) or the reject link.
The Advanced tab allows you to change the default buffering settings for the output links.
