Subject [jira] [Commented] (CASSANDRA-9892) Add support for unsandboxed UDF
Date Mon, 03 Aug 2015 09:29:05 GMT


Robert Stupp commented on CASSANDRA-9892:

{{GRANT CREATE TRUSTED FUNCTION TO ...}} could be the privilege to create non-sandboxed functions.
But it would require some extension to the authz code + schema.

{{GRANT CREATE TRUSTED TO ...}} could be an additional privilege required to create non-sandboxed
functions (in addition to CREATE FUNCTION privilege).

{{GRANT TRUST FUNCTION TO ...}} would be a new permission (thus requiring CREATE + TRUST permissions).

> From discussion on CASSANDRA-9402,
> The approach postgresql takes is to distinguish between "trusted" (sandboxed) and "untrusted"
(anything goes) UDF languages. 
> Creating an untrusted language always requires superuser mode. Once that is done, creating
functions in it requires nothing special.
> Personally I would be fine with this approach, but I think it would be more useful to
have the extra permission on creating the function, and also wouldn't require adding explicit
> So I'd suggest just providing different CQL permissions for trusted and untrusted, i.e.
if you have CREATE FUNCTION permission that allows you to create sandboxed UDF, but you can
only create unsandboxed if you have CREATE UNTRUSTED.
