Jonathan Ellis commented on CASSANDRA-1311:
-------------------------------------------

It's not the synchronicity per se that's interesting, so much as the part about 
making them per-replica rather than per-coordinator so we can guarantee 
consistency via the commitlog.

> Support (asynchronous) triggers

> 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.
> Please find the motivation, triggers description and list of applications:
