[jira] [Commented] (CASSANDRA-3541) Support timeuuid column names

    [ https://issues.apache.org/jira/browse/CASSANDRA-3541?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13160126#comment-13160126 ] 

Brandon Williams commented on CASSANDRA-3541:
---------------------------------------------

When you pass an invalid comparator, it throws a traceback instead of just saying it's invalid.  Also, it's case-sensitive which is slightly annoying but I can live with that.  Out of curiosity, why both UTF-8 and Ascii?

> Real-world Cassandra applications often use "wide rows" to denormalize queries into.  Most often, this means they do a lot of appending to existing rows, with few overwrites.  An easy way to add this to Stress would be to allow specifying timeuuid column names (which will be inherently sequential, or nearly so).  For forwards-compatibility, we could add a --comparator option that only supports the existing Ascii type and the proposed UUID type, to start with.
