Hello, I am migrating from prefect v1 to v2.10.* I am not sure how to use this can someone help me out? from prefect.executors import LocalDaskExecutor Should I use prefect_dask imports for this?

Yep. Check out the prefect-dask docs and the Prefect docs guide on Dask and Ray for info and examples. 🙂

I am still confused

I think you need to specify the number of workers in an argument to the DaskTaskRunner, like in the example here:

DaskTaskRunner(
    cluster_class="dask_cloudprovider.FargateCluster",
    cluster_kwargs={
        "image": "prefecthq/prefect:latest",
        "n_workers": 5,
    },
)

Hello just to confirm what is the use of this image tag in the cluster?

That’s the Docker image that will pull the latest Prefect image in this case.

Here's an example of the weird internal error Dask (I think) is throwing on production: "sqlalchemy.exc.OperationalError: (sqlite3.OperationalError) database is locked [SQL: INSERT INTO task_run (task_key, dynamic_key, cache_key, cache_expiration, task_version, flow_run_run_count, empirical_policy, task_inputs, tags, flow_run_id, name, run_count, total_run_time, id, created, updated) VALUES (:task_key, :dynamic_key, :cache_key, :cache_expiration, :task_version, :flow_run_run_count, :empirical_policy, :task_inputs, :tags, :flow_run_id, :name, :run_count, :total_run_time, :id, :created, :updated) ON CONFLICT (flow_run_id, task_key, dynamic_key) DO NOTHING]" I am facing such an error have any suggestions for me

Looks like a sqlite error. You'll want to use Postgres or Prefect Cloud in production.

If it's not too much to ask for can you guide me on what changes would be required I am new to this library and I don't have much production experience.

Using Prefect Cloud as the API server backend would be the simplest way to get going. Here’s the quick start.
