Subject [jira] Created: (HDFS-926) BufferedDFSInputStream
Date Tue, 26 Jan 2010 16:08:34 GMT
BufferedDFSInputStream
----------------------

                 Key: HDFS-926
                 URL: https://issues.apache.org/jira/browse/HDFS-926
             Project: Hadoop HDFS
          Issue Type: Wish
          Components: hdfs client
            Reporter: Zlatin Balevsky
            Priority: Minor


Self-explanatory.  Buffer size can be provided in number of blocks.  Could be implemented
trivially with heap storage and several BlockReaders or could have more advanced features
like:

* logic to ensure that blocks are not pulled from the same Datanode(s).
* local filesystem store for buffered blocks
* adaptive parallelism
