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

With the current state of trunk, native compression only works on Linux anyway 
without reworking the entire libhadoop structure.  See HADOOP-7405.

> Integrate Snappy compression

> 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.
