[jira] [Commented] (CASSANDRA-7557) User permissions for UDFs

["Robert Stupp (JIRA)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/CASSANDRA-7557?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14091890#comment-14091890 ] 

Robert Stupp commented on CASSANDRA-7557:
-----------------------------------------

Evaluation:
* {{CREATE}} and {{DROP}} permissions are basically handled in CASSANDRA-7395.
* {{EXECUTE}} permission for {{SELECT}} is basically easy to add (add check to {{Selection.SelectionWithFunctions}} class).
* But since functions might be executed at CQL parse time (any of the {{prepare}} methods via {{Cql.g}} in {{CqlParser}}) permission check for UDFs used in terms/operators is not that easy.

> We probably want some new permissions for user defined functions.  Most RDBMSes split function permissions roughly into {{EXECUTE}} and {{CREATE}}/{{ALTER}}/{{DROP}} permissions.
