Subject [jira] Commented: (HADOOP-6837) Support for LZMA compression
Date Wed, 23 Jun 2010 22:41:54 GMT

    [ https://issues.apache.org/jira/browse/HADOOP-6837?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12881934#action_12881934
] 

Greg Roelofs commented on HADOOP-6837:
--------------------------------------

LZMA is not faster than gzip/bzip2; it compresses better.  FastLZ (next item on Nicholas's
plate) is faster than LZO but compresses more poorly than everything else (except maybe LZW).
 They're both useful, but they address different parts of the problem domain.

higher compression ratios than both gzip and bzip2.
