Subject [jira] Commented: (HADOOP-3315) New binary file format
Date Mon, 12 May 2008 09:19:55 GMT

    [ https://issues.apache.org/jira/browse/HADOOP-3315?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12596012#action_12596012

Enis Soztutar commented on HADOOP-3315:
---------------------------------------

We should not depend on keys/values being Writables in TFile, the API should be : 
{code}

public class TFile<K extends Comparable<K>, V> {
  public static class Writer<K extends Comparable<K>, V> {
     void append(K key, V value);
     Class<K> getKeyClass();
     ...
  }
  public static class Reader<K extends Comparable<K>, V> {
    V get(K key, V val) ;
    boolean next(K key, V val);
    ...
  }
}

{code}

> SequenceFile's block compression format is too complex and requires 4 codecs to compress
or decompress. It would be good to have a file format that only needs
