Subject [jira] Created: (HBASE-2404) native fast compression codec
Date Fri, 02 Apr 2010 17:10:27 GMT
native fast compression codec
-----------------------------

                 Key: HBASE-2404
                 URL: https://issues.apache.org/jira/browse/HBASE-2404
             Project: Hadoop HBase
          Issue Type: New Feature
            Reporter: Andrew Purtell


We often recommend enabling LZO on tables, most users see big wins. LZO is roughly comparable
to BigTable LZW, also the way HFile uses LZO has functional equivalence to prefix compression
on keys. However, LZO is GPL licensed, so a series of install steps are required: http://wiki.apache.org/hadoop/UsingLzoCompression
. It's easy to miss a step or get it wrong. If so, all writes on a table (re)configured to
use LZO will fail. 

Hadoop, well, Java, has native support for gzip compression but it is too slow generally;
is a good option however for archival tables. 

This issue is about considering bundling or creating a comparable alternate to LZO which is
ASF 2.0 license compatible.
