 <div class="block"><p>Topology configs are specified as a plain old map. This class provides a convenient way to create a topology config map by providing setter methods for all the configs that can be set. It also makes it easier to do things like add serializations.</p><p>This class also provides constants for all the configurations possible on a Storm cluster and Storm topology. Each constant is paired with an annotation that defines the validity criterion of the corresponding field. Default values for these configs can be found in defaults.yaml.</p><p>Note that you may put other configurations in any of the configs. Storm will ignore anything it doesn&rsquo;t recognize, but your topologies are free to make use of them by reading them in the prepare method of Bolts or the open method of Spouts.</p></div>
