Hi , anyone tried airflow and use along with an existing flink cluster together? Any documentation around this?

How would you be using them together? Airflow just runs code on a schedule, so it should be quite trivial to launch flink jobs from it. You might want to look into deferrable operators if the job is long running.

Can be for flink Cluster provisioning and job submissions to be automated,.. should be able to submit and manage jobs from Apache Airflow.

You might need to write your own operator to make it work with your infrastructure, but if it can be defined in code then Airflow can run it on a schedule

I'm assuming that you're thinking about Airflow in a batch / bounded mode only, given that streaming / unbounded applications are never ending
