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 > 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 > Assignee: Adrien Grand > Priority: Minor > Fix For: 1.2.2 > > Attachments: CASSANDRA-5038.patch, CASSANDRA-5038.patch, > 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.
