Subject [jira] [Commented] (ACCUMULO-351) Add support for LZ4 compression
Date Thu, 05 Sep 2013 01:32:52 GMT

    [ https://issues.apache.org/jira/browse/ACCUMULO-351?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13758650#comment-13758650
] 

Mike Drob commented on ACCUMULO-351:
------------------------------------

Are the options for compression codecs pluggable? Seems like it would be nice to just have
a compressor/decompressor interface and tell people that they can just throw implementations
in lib/ext.

Does Accumulo do much with the compressors other than toss them over to HDFS for getting codecs?

> LZ4 is like LZ0, but with better decompression rates and it's BSD license, which means
we can incorporate it in svn. Information about it is found here http://code.google.com/p/lz4/
. Additionally, there exists a JNI library for it (and snappy, for ACCUMULO-139 ) at https://github.com/decster/jnicompressions
. I did not find the license for that, but it's a potential option.
