Yeah, the problem is there's no query.conf or schema.sql in there yet, because I wasn't convinced the ones included in the gist were correct. The gist author used non-standard table column for everything as well, which makes this harder... and seems to be doing some crazy time based expiry, which is pretty cool, but not how the rest of the dialects operate.

Because of Cassandra's architecture, it's impossible to get the affected row count, so you can't do the alt query failover thing you can with the other dialects.

The queries should likely all be UPDATEs with a condition comparing Last-Updated to Event-Timestamp. I'll look at it more today.
