Subject [jira] [Commented] (CASSANDRA-47) SSTable compression
Date Tue, 26 Jul 2011 16:17:10 GMT

    [ https://issues.apache.org/jira/browse/CASSANDRA-47?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13071191#comment-13071191

Sylvain Lebresne commented on CASSANDRA-47:
-------------------------------------------

bq. This should be a per-cf option IMO with a default of "compressed"

I'm -1 on the default to compressed. This would mean upon upgrade, people would get their
file compressed unless they do something about it. This is new code and we're talking about
the data files. I will be happy to set the default to compressed in a year, but not now.

> We should be able to do SSTable compression which would trade CPU for I/O (almost always
a good trade).
