Subject Re: Trigger and customized filter
Date Tue, 10 Jul 2012 15:06:51 GMT
While Jonathan and crew work on the infrastructure to support triggers:
https://issues.apache.org/jira/browse/CASSANDRA-4285

We have a project going over here that provides a trigger-like capability:
https://github.com/hmsonline/cassandra-triggers/
https://github.com/hmsonline/cassandra-triggers/wiki/GettingStarted

We are working enhancements that would support synchronous triggers w/
javascript.
For now, they are processed asynchronously, and you implement a Java interface.
