bq. A quick glance at the implementation looks like its doing Slave hashing
based only on its IP address, would this cause problems with hosts running
multiple Cassandra instances on a single IP address?
You already can't have multiple Cassandra instances on a single IP.

> Asynchronous triggers is a basic mechanism to implement various use cases of
> asynchronous execution of application code at database side. For example to
> support indexes and materialized views, online analytics, push-based data
> propagation.
