celery

Celery is an open-source asynchronous task queue or distributed task queue, which is used to execute tasks outside the main application flow. It enables you to perform resource-intensive, time-consuming, or external operations asynchronously, without blocking the user-facing application. Celery communicates via messages, usually using a message broker (like RabbitMQ or Redis) to pass tasks between clients and workers. Workers are separate processes that execute the tasks. This is useful for scenarios like sending emails, processing images, or any other background job, thus improving application responsiveness and scalability.
