Subject Re: Maximum Value Size

You should definitely upgrade to 0.4, it might mean using raw Thrift
but we have at least one person doing that in Perl.  (Is
Net::Cassandra much more than a thin wrapper anyway?)

Cassandra isn't optimized for blob support (see for one proposal
to fix this) but 20MB should be doable.
