Doug Cutting commented on HADOOP-4874:
--------------------------------------
The fastlz guy has benchmarks showing he's faster decompressing than lzf.
http://www.fastlz.org/lzf.htm
YMMV, but either look fine. If we could find something that has a command-line
executable that is already distributed with linux that might be a tiebreaker,
but I don't see any such. Or if we could find a Java implementation of either.
There's a java LZF at:
http://h2database.googlecode.com/svn/trunk/h2/src/main/org/h2/compress/
This is under EPL and MPL, both category B in
http://www.apache.org/legal/3party.html.
I can't find a java implementation of fastlz, but we could probably write one
if we wanted. There's not much code there. So I guess this tilts things in
favor of lzf?
