Subject [jira] [Commented] (HADOOP-7206) Integrate Snappy compression
Date Wed, 23 Mar 2011 17:16:06 GMT

    [ https://issues.apache.org/jira/browse/HADOOP-7206?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13010230#comment-13010230

Allen Wittenauer commented on HADOOP-7206:
------------------------------------------

The disadvantage is that it is yet another reason not to get an Apache release out.  After
all, if all the 'good bits' have been back ported, why move forward?

So no, please don't break it out, please don't back port.  Or is the goal to see if we can
make it to three years before we get a new, solid release out the door?

> Google release Zippy as an open source (APLv2) project called Snappy (http://code.google.com/p/snappy).
This tracks integrating it into Hadoop.

> Snappy is a compression/decompression library. It does not aim for maximum compression,
or compatibility with any other compression library; instead, it aims for very high speeds
and reasonable compression. For instance, compared to the fastest mode of zlib, Snappy is
an order of magnitude faster for most inputs, but the resulting compressed files are anywhere
from 20% to 100% bigger. On a single core of a Core i7 processor in 64-bit mode, Snappy compresses
at about 250 MB/sec or more and decompresses at about 500 MB/sec or more.
