Jonathan Ellis commented on CASSANDRA-2474:
-------------------------------------------
Illustration time. (See: screenshot-1.jpg)
We have a "wide row" of stock histories. Just "normal" columns, no composites
or supercolumns.
We could use transposition syntax to get these as "normal" (not sparse)
resultset:
{code}
SELECT date, value
FROM stockhist
WHERE symbol='GOOG'
AND date >= '2011-01-02'
LIMIT 50
{code}
Which would yield
{noformat}
date value
2011-01-02 $75.23
2011-01-03 $82.11
{noformat}
> 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.
