Celery apply vs apply_async

WebCelery uses headers to store the content type of the message and its content encoding. The content type is usually the serialization format used to serialize the message. The body contains the name of the task to execute, the task id (UUID), the arguments to apply it with and some additional meta-data – like the number of retries or an ETA. WebThese three methods - delay(), apply_async(), and applying (__call__), make up the Celery calling API, which is also used for signatures. A more detailed overview of the Calling API can be found in the Calling User Guide. Every task invocation will be given a unique identifier (an UUID) – this is the task id.
