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:
begin batch using consistenc
I see now there is a package org.apache.cassandra.cql3.statements, with
BatchStatement class. Is this what I should use?

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.
On 10 July
n't work at all, but also because the whole point of CQL3 is to hide
that kind of complexity.

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

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 ta
