>             Project: Spark
>          Issue Type: Sub-task
>          Components: PySpark
>    Affects Versions: 3.1.0
>            Reporter: Maciej Szymkiewicz
>            Priority: Major

> At the moment, with exception to type ignores, we use default MyPy configuration. These already provide decent coverage, but are somewhat less restrictive than the ones used in {{typeshed}} and {{pyspark-stubs}}.
> We should consider at least the following:
> - {{strict_optional}}
> - {{no_implicit_optional}}
> It might be also a good idea to add {{disallow_untyped_defs}}, which will allow us to catch any instances of user-facing code, that are missing annotations.
