<@U01690HA6E8> I don't advise using a filesystem cache if this is a production system. You need to setup a result's cache and would advise to use celery workers also\nHere's an example for setting up celery and a results cache:\n```from werkzeug.contrib.cache import RedisCache\n\n...\n\nclass CeleryConfig(object):\n    BROKER_URL = "<redis://localhost:6379/0>"\n    CELERY_IMPORTS = ("superset.sql_lab", "superset.tasks")\n    CELERY_RESULT_BACKEND = "<redis://localhost:6379/0>"\n    CELERYD_PREFETCH_MULTIPLIER = 10\n    CELERY_ACKS_LATE = True\n\nCELERY_CONFIG = CeleryConfig\n\nRESULTS_BACKEND = RedisCache(host='localhost', port=6379, key_prefix='superset_results')```
