> Key: AIRFLOW-3916
> URL: https://issues.apache.org/jira/browse/AIRFLOW-3916
> Project: Apache Airflow
> Issue Type: Improvement
> Components: executor, kubernetes, worker
> Affects Versions: 1.10.1, 1.10.2
> Reporter: raman
> Priority: Major
> Labels: kubernetes
>
> Currently K8 Worker pod uses Metastore for continuous heartbeat which might make metastore a bottleneck for 1000(s) of running Pods.
> Airflow with K8 Executor mode uses KubernetesJobWatcher to track the status for submitted worker pod(s). It can be leveraged to remove the worker pod's dependency on Meta store for heartbeating.
