How to Configure a Fact Retriever for a Policy
You can store facts that do not change frequently, and then before the first execution cycle of your host application, you can retrieve these facts from storage, present them once to the rule engine for caching, and reuse them over multiple execution cycles.
There are two ways to associate a fact retriever with a policy. You can do this by using the Business Rule Composer or programmatically by using the RuleSetExecutionConfiguration object.
Note
Only one fact retriever implementation can be associated with a policy version.
To associate a fact retriever with a policy in the Business Rule Composer
In the Policy Explorer window, click the policy version with which you want to associate the fact retriever.
In the Properties window, click the ellipsis button (…) in the FactRetriever property to browse in the global assembly cache for a fact retriever object.
Important
The ellipsis button (…) does not appear until you click the FactRetriever row in the Property Window.
