Todd Lipcon commented on HADOOP-7206:
-------------------------------------
Hi Issei. Thanks for starting the work to port Snappy to a compression codec!
The only concern I have with your codebase is that it seems to be derived from
the hadoop-lzo codebase, which has portions of the Java code licensed under the
GPL.
As I understand it, so long as all of the copyright owners (ie authors) of the
LZO codebase agree, we can relicense the Java portions of that code as Apache
or BSD. I believe the main author list is:
- me
- Kevin Weil
- Owen O'Malley
- Hong Tang
- Chris Douglas
Do others agree with this assessment?
> 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.
