Active and Passive Mapplets

When you configure a mapplet, you specify whether the mapplet is active or passive.

An active mapplet uses a mapplet that includes at least one active PowerCenter transformation. An active mapplet can return a number of rows different from the number of source rows passed to the mapplet. For example, an active mapplet might aggregate five source rows and return one row.

A passive mapplet uses a mapplet that includes only passive PowerCenter transformations. A passive mapplet returns the same number of rows that are passed from the source.
