In the Output page, you can specify details about how the External Source stage reads data from an external program. You can choose to look at details of the main output link or the reject link. The tabs in this stage allow you specify various options for the output link.

The Output page allows you to specify details about how the External Source stage reads data from an external program. The External Source stage can have only one output link. It can also have a single reject link, where rows that do not match the expected schema can be sent. The Output name drop-down list allows you to choose whether you are looking at details of the main output link (the stream link) or the reject link.

The General tab allows you to specify an optional description of the output link. The Properties tab allows you to specify details of exactly what the link does. The Format tab gives information about the format of the files being read. The Columns tab specifies the column definitions of the data. The Advanced tab allows you to change the default buffering settings for the output link.

Details about External Source stage properties and formatting are given in the following sections. See "Stage Editors," for a general description of the other tabs.
