Jonathan Ellis commented on CASSANDRA-5038:
-------------------------------------------

Is there a valid reason to stick with Snappy now?  E.g. are there workloads where it would compress better?

> LZ4 is a new compression algo that's ~2x faster than Snappy.
> [~jpountz] has written a nice java port which includes a misc.Unsafe version that performs >= than our java snappy version.
> Details at http://blog.jpountz.net/post/28092106032/wow-lz4-is-fast
> The nice thing is this should work with java7 and be more portable.
> We can also fallback the pure java impl
