Eric Evans commented on CASSANDRA-1704:
---------------------------------------
bq. It tells it how to turn column names into byte[]:
Oh, I see. Yeah I'm not sure I'm a fan of that. I'd planned to handle that
with different term definitions.
{code:SQL}
; So instead of...
SELECT 10000 MARSHAL AS Long FROM ...
; ...you'd have a term syntax that meant "long"
SELECT 10000L FROM ...
; Instead of...
SELECT 12345678-1234-5678-1234-567812345678 MARSHAL AS TimeUuid FROM ...
; ...you'd do
SELECT TIMEUUID(12345678-1234-5678-1234-567812345678) FROM ...
{code}
And something like a TimeUuid ought to also be possible with string formatted
dates, numeric timestamps, or in the case of an UPDATE, an argument-less
version that means "now".

> Key: CASSANDRA-1704
> URL: https://issues.apache.org/jira/browse/CASSANDRA-1704
> Project: Cassandra
> Issue Type: Sub-task
> Components: API
> Affects Versions: 0.8
> Reporter: Eric Evans
> Priority: Minor
> Fix For: 0.8
>
> Original Estimate: 0h
> Remaining Estimate: 0h
>
> Data access specification and implementation for CQL.
> This corresponds to the following RPC methods:
> * get()
> * get_slice()
> * get_count()
> * multiget_slice()
> * multiget_count()
> * get_range_slices()
> * get_indexed_slices()
> The initial check-in to trunk/ uses a syntax that looks like:
> {code:SQL}
> SELECT (FROM)? <CF> [USING CONSISTENCY.<LVL>] WHERE <EXPRESSION> [ROWLIMIT X]
> [COLLIMIT Y] [ASC|DESC]
> {code}
> Where:
> * <CF> is the column family name.
> * <EXPRESSION> consists of relations chained by the AND keyword.
> * <LVL> corresponds to one of the enum values in the RPC interface(s).
> What is still undone:
> * Support for indexes
> * Counts
> * Complete test coverage
> And of course, all of this is still very much open to further discussion.
