Thanks for the reply. The newest version of the module I see on CPAN is
0.08b. I actually had 0.07 installed and am using 0.6beta3 for
cassandra. Is there somewhere else I should look for the 0.09 version of
the module? I'll also upgrade to the release candidate version of
Cassandra and see if that helps.

Mike, you can submit bugs and questions directly to me, here, or through
http://rt.cpan.org (the CPAN bug tracker). It's a good idea to test an
operation from the CLI that comes with Cassandra to make sure the
problem is not with the Net::Cassandra::Easy module.
Also, if you set $Net::Cassandra::Easy::DEBUG to 1, you'll see the
actual Thrift objects that get constructed. In this case (N::C::Easy
0.08) I was constructing a super_column parameter which was wrong.

It's a bug in N::C::Easy. I fixed it in 0.09 so it will work properly with:
$rc = $c->mutate([$key], family => 'Standard1', deletions => { standard => 1,
byname => ['column1', 'column2']});
AFAIK I can't specify "delete all columns in a non-super CF" using
Deletions so "byname" is required (I end up filling the column_names
field in the predicate). OTOH I can just delete a SuperColumn so the
above is possible in a super CF.
The docs and tests were updated as well. Let me know if you have
problems; it worked for me. In the next release I'll update cassidy.pl
to work with non-super CFs as well. Sorry for the inconvenience.
Thanks
Ted
