John Arnold created AIRFLOW-2367:
------------------------------------
Summary: High POSTGRES DB CPU utilization
Key: AIRFLOW-2367
URL: https://issues.apache.org/jira/browse/AIRFLOW-2367
Project: Apache Airflow
Issue Type: Bug
Components: scheduler
Affects Versions: Airflow 2.0, 1.9.0
Reporter: John Arnold
We are seeing steady state 70-90% CPU utilization. It feels like a missing
index kind of problem, as our TPS rate is really low, I'm not seeing any long
running queries, connection counts are reasonable (low hundreds) and locks also
look reasonable (not many exclusive / write locks)
We shut down the webserver and it doesn't go away, so it doesn't seem to be in
that part of the code. My guess is either the scheduler has an inefficient
query, or the (Celery) executor code path does.
