Subject [jira] [Created] (HADOOP-7206) Integrate Snappy compression
Date Tue, 22 Mar 2011 23:46:05 GMT
Integrate Snappy compression

                 Key: HADOOP-7206
                 URL: https://issues.apache.org/jira/browse/HADOOP-7206
             Project: Hadoop Common
          Issue Type: New Feature
            Reporter: Eli Collins

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.
