Subject [jira] [Updated] (CASSANDRA-3761) CQL 3.0
Date Tue, 24 Jan 2012 13:48:40 GMT


Sylvain Lebresne updated CASSANDRA-3761:

    Attachment: 0004-Thrift-gen-files-v2.patch

Attached rebased and update patch set. I've mainly:
* Refactored a bit using the 'builder approach' I talked earlier on. It does simplify a bunch
of case. I've removed the CFDefinition.Kind enum and instead keep just two isComposite and
isCompact flags. It's equivalent to the previous enum but maybe more clear and in any case
we now have the code for dense and dynamic that are always shared, and the one for static
and sparse almost always too.
* Removed support for adding non-EQ clause on the row keys with RP (we'll deal with it in
* Change the behavior of selecting on composite without giving all the components. It'll now
select all the record having the given prefix (for which we don't really need CASSANDRA_3237).
Ok for adding null support later

To avoid rebase problem I've also pushed the branch on
For the tests, I have them all passing here, but for the 'assert_invalid', I added it to dtests
but forgot to push it publicly. I've created
with an updated version of the tests (I only tested on this branch so far).

> 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).
