In one embodiment, a system includes logic adapted for receiving a first request to change a state of a first group of catalogs, determining which of a plurality of catalogs belong in the first group, adding a change request for each of the first group of catalogs to a queue for processing, causing processing of each change request in the queue to change the state of each of the first group of catalogs according to the first request, creating a first group result indicating successful or failed state change upon a catalog in the first group of catalogs finishing processing, passing the first group result to an adjacent catalog in the first group of catalogs, removing each catalog that has finished processing from the first group of catalogs, and outputting the group result when there are no adjacent catalogs available to pass the group result.
