> (Follow-up to CASSANDRA-9402)
> TL;DR this ticket is about to add an other config option to enable scripted UDFs.
> Securing Java-UDFs is much easier than scripted UDFs.
> The secure execution of scripted UDFs heavily relies on "how secure" a particular script provider implementation is. Nashorn is probably pretty good at this - but (as discussed offline with [~iamaleksey]) we are not certain. This becomes worse with other JSR-223 providers (which need to be installed by the user anyway).
> E.g.:
> {noformat}
> # Enables use of scripted UDFs.
> # Java UDFs are always enabled, if enable_user_defined_functions is true.
> # Enable this option to be able to use UDFs with "language javascript" or any custom JSR-223 provider.
> enable_scripted_user_defined_functions: false
> {noformat}
> TBH: I would feel more comfortable to have this one. But we should review this along with enable_user_defined_functions for 4.0.
