Subject Re: large number of messages from celeryev pile up in rabbitmq
Date Sun, 18 Jun 2017 13:55:00 GMT
Hi Dima,

do you use RabbitMQ as the Celery result backend?
If so try using e.g. Redis as result backend (parameter
"celery_result_backend" in the airflow.cfg) while
keeping RabbitMQ as the message broker (broker_url).
