Subject [jira] [Updated] (CASSANDRA-2474) CQL support for compound columns and wide rows
Date Mon, 16 Jan 2012 11:38:43 GMT

     [ https://issues.apache.org/jira/browse/CASSANDRA-2474?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

Sylvain Lebresne updated CASSANDRA-2474:
----------------------------------------

    Attachment: 3742.patch

Attaching patch implementing the idea described above (includes a unit test).

Note that when this option is used the patch does not trim the result post-reconciliation
of the result of the different replicas. The reason being that this can be done more simply
and more efficiently on the CQL side (i.e, after the creation of the CqlResult object).

> 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.
