CorrelationQuery

Remarks

A CorrelationQuery is a set of queries that are run on an incoming or outgoing message to generate a set of instance keys. An InstanceKey represents an association between the data selected from the query and a particular service instance.

The Where clause allows the user to filter the set of messages that this CorrelationQuery runs on. The Select clause represents the query set used to uniquely identify the service instance for which an incoming message should be dispatched. The SelectAdditional clauses are a set of query sets that represent new instance keys that must be created to associate that data with the service instance.
