From a3275a7ee9272563718e7e6a3134b392a71da097 Mon Sep 17 00:00:00 2001 From: Ephraim Anierobi Date: Thu, 10 Oct 2024 17:41:36 +0100 Subject: [PATCH 01/49] AIP-65: Add DAG versioning support This commit introduces versioning for DAGs Changes: - Introduced DagVersion model to handle versioning of DAGs. - Added version_name field to DAG for use in tracking the dagversion by users - Added support for version retrieval in the get_dag_source API endpoint - Modified DAG execution logic to reference dag_version_id instead of the dag_hash to ensure DAG runs are linked to specific versions.
