How can you configure the number of worker processes in Celery for task execution?

In Celery, the number of worker processes (worker concurrency) can be configured using the -c (or --concurrency) parameter when starting the worker. This parameter determines how many tasks can be executed in parallel within a single worker.

Example of starting a worker with 4 worker processes:

celery -A your_project worker -c 4

You can also set this value in the Celery configuration, for example:

app.conf.worker_concurrency = 4

If not explicitly specified, Celery usually sets the number of processes equal to the number of CPU cores.
