An asynchronous aggregation pattern continues where the previous splitter pattern ended. By implementing this pattern, you can aggregate results of processed, smaller messages into a large message. Each processed message represents an individual unit of work that has no dependency on other messages. It can be useful when a client sends a batch to be processed and expects a batch response, with results for each message in the batch.
Open Visual Studio 2010 and create a solution for the debatching process. For reference, you can download the source code (
BTS.Cookbook.AsyncAggPattern) belonging to this chapter.
First, you will debatch the message using the Implementing the
