Subject [jira] [Commented] (CASSANDRA-2474) CQL support for compound columns and wide rows
Date Fri, 13 Jan 2012 14:29:40 GMT

    [ https://issues.apache.org/jira/browse/CASSANDRA-2474?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13185605#comment-13185605

Jonathan Ellis commented on CASSANDRA-2474:
-------------------------------------------

bq. now that I think of it, ORDER DESC will have a similar problem to LIMIT for range slice

You're right.  I guess we could just disallow it unless there is also a WHERE clause on the
row key...

> For the most part, this boils down to supporting the specification of compound column
names (the CQL syntax is colon-delimted terms), and then teaching the decoders (drivers) to
create structures from the results.
