Adrien Grand commented on CASSANDRA-5038:
-----------------------------------------
bq. 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).
For your information [~cowtowncoder] ran his JVM compressor benchmark again recently, and
indeed, it shows good performance numbers for both the native and the Java impl of LZ4: https://twitter.com/cowtowncoder/status/343881969697951744

> 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
