Subject [jira] [Created] (CASSANDRA-6871) Dynamic class loading for triggers (and udfs)
Date Sun, 16 Mar 2014 18:18:42 GMT
Edward Capriolo created CASSANDRA-6871:

             Summary: Dynamic class loading for triggers (and udfs)
                 Key: CASSANDRA-6871
             Project: Cassandra
          Issue Type: New Feature
            Reporter: Edward Capriolo
            Assignee: Edward Capriolo

Currently the trigger feature requires out of band shipping jar files to servers. In the near
future users may be able to provide custom functions like trim() dynamically like pig and
hive do. In order to accomplish this securely my suggestion is this.

1. Add a new configuration knob to cassandra.yaml which controls how users are allowed to
load class definitions. 


2. Add the to the project as a dependency.

3. Profit: A follow on piece would allow triggers to be defined in a JVM language. Features
like could use this. Users can also create
different pluggable components to CQL at runtime. 

This issue would just be about brining the dynamic loading mechanism in the project securely.
Not implementing it in a user facincg way.
