Hello,
I am experimenting with cassandra 1.2.2 and are interested in using the
native LZ4 compressor in linux. I have built the linux library but aren't
sure how to tell tell cassandra to use it.
Do I just drop it in the cassandra lib directory and change the compression
for my column family?

http://repo1.maven.org/maven2/net/jpountz/lz4/lz4/1.1.0/lz4-1.1.0.jar

in the jar file. I'll
