Duplicate tasks

[belgacea]

Hi, I'm facing an old issue (1) (2) using Celery with Django default db backend (sqlite). It seems that tasks in CELERYBEAT_SCHEDULE env var are created in db at each execution of beat/worker, so it duplicates tasks.. I'm new to Celery, can someone explain me why tasks are saved in a database while they already exist in the conf file? Also, is there an option (or something else) to avoid duplicates ? Thx
