Hi Pablo,

I'm refering to the MonetDB feature that allows to create R functions that run embedded in the database.

For example, you can do:

CREATE FUNCTION rapi00() RETURNS TABLE (d INTEGER) LANGUAGE R { seq(1,10); };

Now, I need my users to create dynamically these user defined functions by letting them enter these on the UI; the application will create the function in the database and a process will run them.

Problem is that R allows to run operating system level commands, such as

list.files(path=".")

or even

file.remove("some_file")

Will MonetDB allow these external interactions with the operating system, or it runs in a sandbox? There is no sandbox. Those things are allowed. This is why creating those functions requires additional privileges.
