Aggregator stage in DataStage: Output tab

Aggregator stage: Output tab

The Output tab allows you to specify details about data output from the Aggregator stage. The Aggregator stage does not transfer input data. It generates new columns. The Aggregator stage can have only one output link.

The Aggregator stage does not transfer input data, instead the stage generates new columns. The Aggregator stage outputs nullable fields therefore columns that receive the output data must be nullable.

The Columns section specifies the column definitions of incoming data. Click Edit at the bottom of the Columns section to specify mapping information. Mapping specifies the relationship between the processed data being produced by the Aggregator stage and the Output columns. The Advanced section allows you to change the default buffering settings for the output link.
