Dan Di Spaltro commented on CASSANDRA-2474:
-------------------------------------------
As a user, this is really hard to follow, however this definitely affects me.
I really bought into CQL to make it so API changes were less brutal.
I also bought in because this was a better user experience, I've used cassandra
for a long time and spinning dev's up on the thrift API was difficult.
Lastly, I imagine this will actually affect the upgrade path for companies
using CQL, just like the reason we never upgraded from 0.6 -> * on a product
was the changeset and amount of moving parts were too great (It wasn't just
that reason, there are other forces at work, don't get me wrong).
These type of things hurt the user community, and need to be treated with care,
especially as this product has really grown into something important to A LOT
of people (like myself).
Just my 2 cents

> 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.
