[jira] [Created] (HADOOP-16317) ABFS: improve random read performance

Da Zhou created HADOOP-16317:
--------------------------------

             Summary: ABFS: improve random read performance
                 Key: HADOOP-16317
                 URL: https://issues.apache.org/jira/browse/HADOOP-16317
             Project: Hadoop Common
          Issue Type: Sub-task
          Components: fs/azure
    Affects Versions: 3.2.0
            Reporter: Da Zhou


Improving random read performance is an interesting topic. ABFS doesn't perform well when reading column format files as the process involves with many seek operations which make the readAhead no use, and if readAhead is used unwisely it would lead to unnecessary data request.

Hence creating this Jira as a reminder to track the investigation and progress of the work.
