Sylvain Lebresne commented on CASSANDRA-2474:
---------------------------------------------

bq. because I've been very clear from the beginning that we do need to support 
the "dense" case

Alright, cool.

bq. We can bikeshed all day about whether "sparse" or "dense" is the more 
common, but bottom line is we need to support both

Agreed. I just felt from the conversation that "dense" was getting really much 
less love that sparse based on the argument that "doing dense is wrong". Since 
I disagree with that argument, I just wanted to make sure we don't pick a 
syntax that discourage "dense" too much (again, which isn't saying we should 
discourage "sparse" either).

One thing I hadn't followed at first was that we planned to deprecate the '..' 
notation in favor for transposed view even for non-composite columns. But now 
that I've connected the dots, that makes sense.

> 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.
