Aggregator Step
The Aggregator step allows you to choose an Aggregator instance to add to a process. The Aggregator component assembles a data object from individual message object. It is done by passing a message object containing a part to the PutMessage action. The Aggregator component must know when all the parts have been provided to produce the complete data object. The input message contains information that indicates the Aggregator on how to become part of a complex object. A typical application for an Aggregator component includes assembling complex documents from discrete parts.
