Subject [jira] [Commented] (HADOOP-7657) Add support for LZ4 compression
Date Thu, 29 Sep 2011 17:41:45 GMT

    [ https://issues.apache.org/jira/browse/HADOOP-7657?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13117462#comment-13117462

Mr Bsd commented on HADOOP-7657:
--------------------------------

As far as i understand, LZ4 is just a compression algorithm, and does not define an output
format.
The one proposed in the open-source file "LZ4Demo" is just an example, and obviously made
to work with pipe, i.e. unseekable input and output.

> According to several benchmark sites, LZ4 seems to overtake other fast compression algorithms,
especially in the decompression speed area. The interface is also trivial to integrate (http://code.google.com/p/lz4/source/browse/trunk/lz4.h)
and there is no license issue.
