code: public StashRowIterator scan(String table)
              throws StashNotAvailableException, TableNotStashedException {
          List<StashSplit> splits = getSplits(table);
          return new StashScanIterator(_s3, _bucket, _rootPath, splits);
      }
docs: Gets an iterator over the entire contents of a Stash table.  If possible the caller should call
  {@link com.bazaarvoice.emodb.common.stash.StashRowIterator#close()} when done with the iterator
  to immediately free any S3 connections.
