Federation Strategy

Description

A Federation Strategy federates a query to all of the Remote Sources in the query's list, processes the results in a unique way, and then returns the results to the client. For example, implementations can choose to block until all results return then do a mass sort, or to return the results back to the client as soon as they are received back from a Federated Source.

Usage

An Endpoint can optionally specify the federation strategy to use when it invokes the query operation. Otherwise, the Catalog provides a default Federation Strategy that will be used.
