Subject [jira] [Commented] (CASSANDRA-2474) CQL support for compound columns and wide rows
Date Fri, 13 Jan 2012 22:56:40 GMT

    [ https://issues.apache.org/jira/browse/CASSANDRA-2474?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13185948#comment-13185948
] 

Eric Evans commented on CASSANDRA-2474:
---------------------------------------

Setting aside any discussion of the specific changes being proposed for a moment, I would
like to point out that I count at least 3 breaking changes to the language (a third new major
language version in as many releases), that we're proposing making these changes late in the
11th hour of the release cycle, and without seeking input from the wider community (I can't
imagine too many people are able to follow this issue any more).

> 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.
