The config that you supply during topology submission is attached to that topology only (1 to 1 mapping). You can add custom param to your config prior to submission and your topology's bolts and spouts will get the config that you submitted as a parameter as part of their prepare method call.

StormSubmitter.submitTopology(name, config, topology) I have a generic topology that has several generic bolts that are to be configured during the prepare. During the prepare they would pull this config parameter as a key to get detailed assets/configuration info that is stored in mongo. I would like to add a parameter to the Config prior to submission topology.assets=someValue someValue would be unique in with each topology submission, but the key, topology.assets, would be same with each topology submission. - Robert D.
