Celery has a large and diverse community of users and yaml, msgpack. zlib, bzip2 compression. Cryptographic message signing. Features Monitoring A stream of monitoring events is emitted by workers and is used by built-in and external tools to tell you a task: >>> result = add.delay(4, 4) The ready() method returns whether the task has finished processing or not: >>> result.ready() False You can wait for the result to complete, but this is rarely
