User: gorzell Date: 1/17/13 Time: 10:18 AM More advanced Dynamo source that allows you to filter the results based on the current deployment context values. Rather than polling dynamo itself this class reads a cache that you have to setup separately. If you used a combined configuration you can cascade these sources to so that certain contexts override others.
