Cassandra trigger explanation

I could not find any proper documentation on Cassandra triggers. Can anyone please explain how they actually work, I mean right from the client making a write request to when the trigger is fired by the coordinator node? If some documentation is present then a link to that would also work.

Whenever the client makes a write query request to the Cassandra cluster, it goes to a coordinator node which first runs the trigger, and then the query is executed in batch logged form.
