Adrien Grand updated CASSANDRA-5038:
------------------------------------

    Attachment: CASSANDRA-5038.patch

I performed a first release of lz4-java yesterday, here is a patch with tests that adds support for lz4 compression. You need to add the lz4 JAR to the lib directory (http://repo1.maven.org/maven2/net/jpountz/lz4/lz4/1.0.0/lz4-1.0.0.jar) before applying it.

This patch is very similar to Jake's Compressor impl, and I especially copied the {{supportedOptions}} method to return {{crc_check_chance}}. What does it change to declare this option as supported? ({{DeflateCompressor}} and {{SnappyCompressor}} just return an empty set.)

Does Cassandra have integration tests that we could try to run with this new compressor?

> 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
