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? > LZ4Compressor > ------------- > > Key: CASSANDRA-5038 > URL: https://issues.apache.org/jira/browse/CASSANDRA-5038 > Project: Cassandra > Issue Type: New Feature > Components: Core > Reporter: T Jake Luciani > Priority: Minor > Fix For: 1.2.2 > > Attachments: CASSANDRA-5038.patch, LZ4Compressor.java, lz4-java.jar > > > 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 -- This message is automatically generated by JIRA.
