Subject [jira] [Commented] (CASSANDRA-5038) LZ4Compressor
Date Fri, 31 May 2013 15:21:21 GMT


Carl Yeksigian commented on CASSANDRA-5038:

One benefit to LZ4 is that the unsafe implementation isn't much slower than the native version;
if we end up going to an incompatible version (or people run on some platform that Snappy/LZ4
native hasn't been created for), they won't have nearly the slowdown that Snappy has (or at
least had, not sure if they've addressed that).
