I¹ll leave it to you guys to decide if it is more elegant to support

I can hack this at the app layer, to issue separate queries for the wrap

I¹m +1.
We¹ve had one foot out the door for a while now.
We are throwing resources at CQL. (e.g. storm-cassandra-cql) And we are
slowing support for the thrift-based implementation (e.g. storm-cassandra).
Alas poor Thrift, I knew him (well).

It feels a little weird, but that will work.
Not a big deal, but maybe we could include a wasApplied() method on the

This caused the CLI to hang and then eventually crashed Cassandra with an
