No data migration. Ploomber Cloud runs on AWS, and can integrate with your existing infrastructure such as S3, GCS, RedShift and Athena.

Ploomber

Yes, you can use two env files (e.g. `env.yaml` and `env.prod.yaml`), then you can switch them at runtime. More in <https://docs.ploomber.io/en/latest/user-guide/configuration.html|the docs>. - does this solve the issue?

something like this where you can just pass an array to parameterize over could be nice but multiple env files will do the job

<https://docs.pytest.org/en/6.2.x/parametrize.html>

you might be looking for the <https://docs.ploomber.io/en/latest/cookbook/grid.html|grid> feature then

can I parameterize outputs based on the grid

yes, we <https://docs.ploomber.io/en/latest/api/spec.html#tasks-grid|added that> in version 0.17.2 so make sure you have that or higher. you need to use `[[` `]]` placeholders

```tasks:
  - source: random-forest.py
    name: random-forest-
    product: 'n_estimators=[[n_estimators]]/criterion=[[criterion]].html'
    grid:
        n_estimators: [5, 10, 20]
        criterion: [gini, entropy]```

is it possible to pass the db client to a py file?

I can import it manually but was wondering if ploomber could help with that

Not at the moment. We got a similar request so we'll work on it soon. But right now you need to import it manually
