        Description copied from class: RoutedAlias
        Ensure our parsed version of the alias collection list is up to date. If it was modified, return true. Note that this will return true if some other alias was modified or if properties were modified. These are spurious and the caller should be written to be tolerant of no material changes.

        Given the route key, finds the correct collection and an indication of any collection that needs to be created. Future docs will potentially cause creation of a collection that does not yet exist. This method presumes that the doc time stamp has already been checked to not exceed maxFutureMs
        Throws:
        SolrException - if the doc is too old to be stored in the TRA
