jpg The broker delivers tasks to the worker nodes. A worker node is a networked machine running celeryd. This can be one or more machines depending on the workload. The result of the task can be stored to import using the -I option to celeryd: $ celeryd -l info -I tasks,handlers This can be a single, or a comma separated list of task modules to import when celeryd starts. Running the celery worker will run the worker server in the foreground, so we can see what’s going on in the terminal: $ celeryd --loglevel=INFO In production you will probably want to run the worker in the background as a daemon

SoftTimeLimitExceeded: clean_up_in_a_hurry() Time limits can also be set using the CELERYD_TASK_TIME_LIMIT / CELERYD_TASK_SOFT_TIME_LIMIT settings. Note Time limits do not currently work on Windows and source C extensions. The option can be set using the workers –maxtasksperchild argument or using the CELERYD_MAX_TASKS_PER_CHILD setting. Autoscaling New in version 2.2. pool support: prefork, gevent The include load average or the amount of memory available. You can specify a custom autoscaler with the CELERYD_AUTOSCALER setting.
