 <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>

This allows the supervisor to select an available version of storm that is compatible with what a topology was launched with.</p><p>Only the major and minor version numbers are used, although this may change in the future. The code will first try to find a version that is the same or higher than the requested version, but with the same major version number. If it cannot it will fall back to using one with a lower minor version, but in some cases this might fail as some features may be missing.</p><p>Because of how this selection process works please don&rsquo;t include two releases with the same major and minor versions as it is undefined which will be selected. Also it is good practice to just include one release for each major version you want to support unless the minor versions are truly not compatible with each other. This is to avoid maintenance and testing overhead.</p><p>This config needs to be set on all supervisors and on nimbus. In general this can be the output of calling storm classpath on the version you want and adding in an entry for the config directory for that release. You should modify the storm.yaml of each of these versions to match the features and settings you want on the main version.</p></div>
