Harsh J commented on HADOOP-7657:
---------------------------------
A good article's here (from author) - wherein he directly compares with snappy:
http://fastcompression.blogspot.com/2011/06/lz4-improved-performance.html
Does seem to have an edge.

> Project: Hadoop Common
> Issue Type: Improvement
> Reporter: Mr Bsd
> Labels: compression

> According to several benchmark sites, LZ4 seems to overtake other fast
> compression algorithms, especially in the decompression speed area. The
> interface is also trivial to integrate
> (http://code.google.com/p/lz4/source/browse/trunk/lz4.h) and there is no
> license issue.
