The CERN Tape Archive (CTA) scheduling system manages the workflow of archive, retrieve, and repack requests, relying on a Scheduler database (Scheduler DB) for transient metadata storage. We present the development of a new relational database (PostgreSQL) backend for the Scheduler DB. The aim is to improve the limitations of the current (object-store based) implementation. This talk will provide a status update on the implementation of archive and retrieve workflows, discuss key advantages of the relational approach, and outline the roadmap..
