Mark,
Thanks for the info. To confirm, If I write my UDFs in Python, they will be executed in parallel (if required)?
Thanks, Dave

Hey Dave,
There's only a single R interpreter running. When an R function is called a lock is acquired that prevents other R functions from running at the same time. There has been some work to running multiple interpreters in parallel in separate processes for Python UDFs, but this has not been ported to R UDFs yet.
Regards,
Mark

All,
Quick question, how many R interpreters are running within MonetDB if you are using R UDFs? Is there a single shared interpreter or are there multiple copies running?
Thanks, Dave
