   > I wonder if these file ranges support us using The HDFS Vectored Read API (https://issues.apache.org/jira/browse/HADOOP-11867)?
   
   I wonder if we would need a new iterator API to able to get the full benefit of this Hadoop API.  In current iterator API one can create deep copies and then seek each one.  If we supported specifying all of the known seeks at once then at lower level we may be able to use this API. Something like the following
   
   ```java
      Collection<Iterator> iterators = iterator.seek(range1, range2, range3);
   ```
