Subject [jira] [Commented] (HADOOP-7206) Integrate Snappy compression
Date Wed, 23 Mar 2011 18:01:06 GMT

    [ https://issues.apache.org/jira/browse/HADOOP-7206?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13010259#comment-13010259

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

I don't really care what Cloudera does as a business.  

But Apache's track history on making everything a separate project to release faster has failed.
 We'd also be better off if folks would resist the temptation to back port anything and everything.


We need to draw the line, and it might as well start here.

> 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.
