Fixes #1528
This PR modifies the default PANDERA_VALIDATION_DEPTH environment setting to
None
. This allows for setting default validation behavior for the polars backend. If the environment variable is not set, then LazyFrame doesn't perform any data-level validation. It will only check schema-level properties of the LazyFrame. This behavior can be overriden by explicitly settingexport PANDERA_VALIDATION_DEPTH=SCHEMA_AND_DATA
.When doing
pl.DataFrame
validation it will perform both schema- and data-level validations.
