Subject [jira] [Commented] (HBASE-8155) Allow Record Compression for HLogs
Date Wed, 20 Mar 2013 20:29:16 GMT

    [ https://issues.apache.org/jira/browse/HBASE-8155?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13608144#comment-13608144
] 

Andrew Purtell commented on HBASE-8155:
---------------------------------------

[~saint.ack@gmail.com] SF can compress either by record or block. I enable SequenceFile.RECORD
compression as part of HBASE-7544 and drop in an encryption codec masquerading as a compression
codec, and it works as expected.

> While HBASE-4608 allows for Key-intelligent log compression & custom extensions,
Hadoop already allows for native compression support with SequenceFile.  We should allow the
user to enable this functionality through the config.  Besides backwards compatibility &
existing stabilized code, allowing users to enable record-level WAL support will allow support
value compression.
