UDXDEVELOPER

The UDXDEVELOPER role is a predefined role that enables users to create and replace user-defined libraries. The dbadmin can grant this role to any user or non-predefined role.

UDXDEVELOPER Privileges

Users with the UDXDEVELOPER role can perform the following actions:

• CREATE LIBRARY
• If library owner or with the DROP privilege:
  • CREATE OR REPLACE LIBRARY
  • DROP LIBRARY
  • ALTER LIBRARY

To use the privileges of this role, you must explicitly enable it using SET ROLE.

Security Considerations

A user with the UDXDEVELOPER role can create libraries and, therefore, can install any UDx function in the database. UDx functions run as the Linux user that owns the database, and therefore have access to resources that Vertica has access to.

A poorly-written function can degrade database performance. Give this role only to users you trust to use UDxs responsibly. You can limit the memory that a UDx can consume by running UDxs in fenced mode and by setting the FencedUDxMemoryLimitMB configuration parameter.
