Sylvain Lebresne commented on CASSANDRA-3761:
---------------------------------------------

@Thorsten:

bq. I assume I can do a column slice using something like

You assume well.

bq. I'm finding it very useful to abuse the wide-row column names a little bit to be able
to group rows

I note your objection and use case. But to be clear, I only meant that the current patch don't
support secondary indexes on wide rows, not that CQL 3 wouldn't ultimately support them. I
just meant that I'd prefer pushing support to a following ticket.

> This ticket is a reformulation/generalization of CASSANDRA-2474. The core change of CQL
3.0 is to introduce the new syntaxes that were discussed in CASSANDRA-2474 that allow to:
> # Provide a better/more native support for wide rows, using the idea of transposed vie.
> # The generalization to composite columns.
> The attached text file create_cf_syntaxes.txt recall the new syntaxes introduced.
> The changes proposed above allow (and strongly suggest in some cases) a number of other
changes to the language that this ticket proposes to explore/implement (more details coming
in the comments).
