-------------------------------------

             Summary: Use skip instead of seek for small forward repositioning 
in DFS streams
                 Key: FLINK-6776
                 URL: https://issues.apache.org/jira/browse/FLINK-6776
             Project: Flink
          Issue Type: Improvement
          Components: State Backends, Checkpointing
            Reporter: Stefan Richter
            Assignee: Stefan Richter


Reading checkpoint meta data and finding key-groups in restores sometimes 
require to seek in input streams. Currently, we always use a seek, even for 
small position changes. As small true seeks are far more expensive than small 
reads/skips, we should just skip over small gaps instead of performing the seek.
