Todd Lipcon commented on HADOOP-7206:
-------------------------------------
Hey Allen. When there are real customers (either external customers in my case
or internal customers at a lot of the bigger companies using Hadoop) who need a
feature, it's not always possible to say no.
Given the choice between putting it in core (and most likely having major users
and distros backport) vs putting it in an external library, I prefer the
external library. I don't follow your reasoning that putting it in core will
speed up an Apache release -- when has adding new code to a project ever made
its release cycle faster?
FWIW I have expressed this same opinion even on projects like HBase where
releases are frequent and people run trees that are very close to the Apache
bits. Keeping projects small makes releases easier, not harder, and
frequent releases means fewer backports.

> Project: Hadoop Common

> 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.
