Head commit for run: 971a123dee955e88955444cf0567ddb941cf6899 / LIU ZHE YOU <[email protected]> Add Celery worker mp_start_method config to curb Python 3.14 memory Python 3.14 changed the Unix multiprocessing default from fork to forkserver (gh-84559). The Celery worker starts its log server and the stale-bundle-cleanup loop (and the optional SecretCache manager) as stdlib multiprocessing.Process children. Under forkserver each re-imports Airflow and spins up extra forkserver/resource-tracker processes, so a 3.13 to 3.14 upgrade inflates the worker's resident memory even though nothing about the workload changed. A new [celery] mp_start_method (falling back to [core] mp_start_method) lets a deployment pin fork to restore the pre-3.14 behaviour. It governs only the worker's stdlib multiprocessing helpers; Celery's prefork pool is driven by billiard, which keeps its own fork default and is unaffected either way.
