         * tricky is that we want to block the calling thread until one of two things happens: (1) all index tables get
         * successfully updated, or (2) any one of the index table writes fail; in either case, we should return as
         * quickly as possible. We get a little more complicated in that if we do get a single failure, but any of the
         * index writes hasn't been started yet (its been queued up, but not submitted to a thread) we want to that task
         * to fail immediately as we know that write is a waste and will need to be replayed anyways.
