[jira] Commented: (CASSANDRA-510) reading from large supercolumns is excessively slow

["Gary Dusbabek (JIRA)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/CASSANDRA-510?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12773232#action_12773232 ] 

Gary Dusbabek commented on CASSANDRA-510:
-----------------------------------------

Just a few noob questions...

Would it be useful to include a test that verifies that an unintended sub column is *not* removed?
Why does cloneMe() call markForDeleteAt?
