Sylvain Lebresne commented on CASSANDRA-2474:
---------------------------------------------
bq. The core difference is that (..,..,..) notation will return given aliases
(category, subcategory) as column names in the results
But how will it do that ?
The result of
{noformat}
SELECT c1:*..c2:*, value FROM events WHERE key = <timestamp>;
{noformat}
would be something like
{noformat}
Key | c1:subc1 | c1:subc2 | c1:subc3 | c2:subc1 |
<timestamp> | event_value1 | event_value2 | event_value3 | event_value4 |
{noformat}
How do the result look like with 'given aliases (category, subcategory) as
column names in the results' ?
> CQL support for compound columns

> 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.
