There are 3 primary use cases of running scripts we've heard from customers.
In this case they would like to have Treasure Data manage the resources the script runs on top of.
We are currently reviewing the feasibility of setting up such a resource processing cluster. Currently, users are able to run & manage scripts from workflows by using the `emr>` operator.
With this operator, users are able to either (a) have a emr-based EC2 machine started and ended around the processing step or (b) connect to an already running EMR cluster.
