Going to hate myself for this, but check out the trigger interface. https://github.com/apache/cassandra/blob/cassandra-3.0/src/java/org/apache/cassandra/triggers/ITrigger.java
Pay attention to the note that says the API is in beta and subject to change. It's had that note for many years, which is an indication of how infrequently anyone uses triggers.
