I thought I'd give this a try:
create columnfamily
at_event__ac_c
(
ac_c text,
ac_creation bigint,
ac_name text,
ac_value text,
PRIMARY KEY (ac_c, ac_creation)
) with compression_parameters:sstable_compression = '';
Then, insert a few columns:

waiting for your confirmation, I am going to try it.

I think he means something like having a fixed set of coiumns in the table
definition, then in the actual rows having other columns not specified in
the defintion, indepentent of the composited part of the PK. When I
reviewed CQL3 for using in Gossie[1] I realized I couldn't have this, and
that it

won't work at all, but also because the whole point of CQL3 is to hide
that kind of complexity.

I am confused then. I remember reviewing the source for CQL3 and finding
that the row reader used the column count in the CF definition in order to
find how many columns it needed to read a single row. I guess I missed a
filter over the composited part or that I reviewed an old version.

you can use the cqlsh help but it will eventually refer you to a cql reference
such as this one that says what the options are. Looks like you need just
'default_validation'.

Thanks Jeremy, but this doesn't work for me. I am using cql3, because I need
new features like composite keys. The manual you pointed to is for 2.0.
I have suspicion that cql3 does not support dynamic tables at all
