Subject [jira] [Commented] (CASSANDRA-3647) Support set and map value types in CQL
Date Tue, 12 Jun 2012 12:22:44 GMT

    [ https://issues.apache.org/jira/browse/CASSANDRA-3647?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13293563#comment-13293563

Jonathan Ellis commented on CASSANDRA-3647:
-------------------------------------------

bq. users can't implement discard as well as we can 

I'd argue that if you cared more about the value than the ordering, you should be using a
Set instead.  And our Sets are inherently ordered (by value), which obviates one of the reasons
to use a List when you really mean a Set in many languages.

bq. I'm not sure I'm convinced by that syntax for sets, as this reuse a very standard notation
for something not standard at all

I'm not sure I follow, what else would S[4] mean?  That is: I'm okay with being non-standard,
as long as it's not ambiguous.

bq. some syntax that were proposed seemed to be a problem for hive

Good point, let's see what Jake says.

> Composite columns introduce the ability to have arbitrarily nested data in a Cassandra
row.  We should expose this through CQL.
