Pausing or resuming an Apache Airflow™ cluster

Pausing stops the main Apache Airflow™ components. The cluster configuration, metadata database, buckets, and credentials are saved.

A weekly cleanup of metadata older than 90 days continues during suspension.

     -n <namespace> \
     --type=merge \
     -p '{"spec":{"pause":true}}'
   

2. Wait for the Paused status:

   kubectl get airflowcluster <cluster_name> \
     -n <namespace> \

After resuming, the scheduler resumes processing DAG files. Check the schedules and task statuses in the web UI.
