---------------------------
Fix Version/s: 1.10.6
> Airflow not scheduling tasks after staying in Running state
> -----------------------------------------------------------
>
> Key: AIRFLOW-6264
> URL: https://issues.apache.org/jira/browse/AIRFLOW-6264
> Project: Apache Airflow
> Issue Type: Bug
> Components: celery, DAG, operators
> Affects Versions: 1.10.6
> Reporter: Nidhi
> Priority: Major
> Fix For: 1.10.6
>
>
> I am trying to run my tasks using Airflow and Celery Executor. I have created
> one DAG inside that I have approximately 60000 tasks. I am trying to run this
> and When I trigger a DAG it starts running but not scheduling my tasks. It
> stays in running state for 2 days without scheduling the tasks.
> And the main bug is If i schedule 5000 tasks then it takes less than 1 minute
> to schedule it but if I am trying to schedule more than that limit it is
> scheduling my tasks.
> I have tried different solutions also to solve this the first one is:
> * *{{PARALLELISM=1000}}*
> * NON_POOLED_TASK_SLOT_COUNT=1000
> * DAG_CONCURRENCY=10000
> *But, this does not work as New Version of airflow does not support
> non_pooled_task_slot_count.*
> *I have tried to use CELERYD_COUNT which is also not working in my case. I
> have tries mostly every changes which can be useful but none of them is
> working for me.*
> *Can someone let me know how can schedule this much amount of tasks /*
