Hi folks, Have been checking the page about dask cluster in K8s (https://docs.prefect.io/orchestration/recipes/k8s_dask.html#dask-cluster-on-kubernetes), and there is an env variable that I cannot figure out why it is useful. Nor finding any info about it. Can someone explain what it is used for :

DASK_DISTRIBUTED__SCHEDULER__BLOCKED_HANDLERS

?

Looks like it was added with the purpose of:

preventing some routes on the scheduler from being called by workers

And the docstring states:

A list of strings specifying a blacklist of handlers to disallow on the Scheduler

https://github.com/dask/distributed/pull/2556

Yea it is not critical to set this environment variable; we should probably remove the reference to it within Prefect

Thanks
