Subject [jira] [Commented] (CASSANDRA-2474) CQL support for compound columns
Date Fri, 06 Jan 2012 12:47:40 GMT


Sylvain Lebresne commented on CASSANDRA-2474:

bq. Speaking of changing stuff, this makes WITH COMPARATOR and WITH VALIDATOR obsolete.

Agreed on the validator, but for the comparator I think it boils down to the question "do
we want to allow 'static' cfs with non-utf8 names?". That is, this ticket makes it unecessary
for the dynamic cfs, but not for static ones. So do we want to allow. I'll admit I have a
hard time coming with a good use of static cf with non-utf8 name though.

> 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.
