I am setting up new cluster for cassandra 1.2.5, and first time using cassandra compression. 
I read about the compressors, and it gathered Snappy Compressor gives better compression but is sslightly slower than LZ4 compressor. Just wanted to know your experience and/or opinions as to Snappy vs LZ4 , which compressor is better in case of huge data, less writes but lots of reads.
