Thorsten von Eicken commented on CASSANDRA-3761:
------------------------------------------------

Question:  in your Standard "dynamic" CF example from create_cf_syntaxes.txt:
{noformat}
CREATE TABLE clicks (
    userid uuid,
    url text,
    timestamp date
    PRIMARY KEY (userid, url)
) WITH COMPACT STORAGE
{noformat}

I assume I can do a column slice using something like:
{noformat}
SELECT timestamp FROM clicks WHERE userid = '...' and url >= '...' and url <= '...';
{noformat}
Correct?

> 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).
