Subject [jira] [Created] (AVRO-1373) Add A XZ Codec
Date Thu, 05 Sep 2013 02:00:55 GMT
Nick White created AVRO-1373:
--------------------------------

             Summary: Add A XZ Codec
                 Key: AVRO-1373
                 URL: https://issues.apache.org/jira/browse/AVRO-1373
             Project: Avro
          Issue Type: New Feature
          Components: java
    Affects Versions: 1.7.5
            Reporter: Nick White
            Assignee: Nick White
         Attachments: xz-codec.patch

The java Avro projects already depend on the commons-library; the attached patch adds support
for the XZ codec using classes from it. I've also refactored some of the duplicated code in
the tools project (the code that deals with the --codec and --level options) by moving a single
copy to the Util class, and calling that from the various tools that produce Avro files. 

The XZ codec by default uses the LZMA2 algorithm to compress files - this produces noticeably
smaller files than the current bzip2 or deflate codecs.
