Hi- A few months back I wrote a Perl client for Cassandra and I realized I never sent it out to this list. While I realize that while Perl is not the language du jour hopefully this will help someone else out. :) Code is periodically thrown up on CPAN but look at http://github.com/mkjellman/perlcassa for the most current version. It supports serialization/deserialization of validation classes, composite columns, as well as connection pooling (without using ResourcePool which fails miserably when run under mod_perl).
