I should have gotten another coffee before writing that mail. Of course
you are right. Splitting the the job would be sufficient. No need to run

All of the data generated in your IT infrastructure is seriously valuable.
Why? It contains a definitive record of application performance, security 
threats, fraudulent activity, and more. Splunk takes this data and makes 
sense of it. IT sense. And common sense.
