MaxGekk commented on issue #26973: [SPARK-30323][SQL] Support filters pushdown in CSV datasource URL: https://github.com/apache/spark/pull/26973#issuecomment-573649775 @cloud-fan I am still worry how does this behave in different modes, especially in the PERMISSIVE mode. Let me write tests for that. In the PERMISSIVE mode, we return `null`s if we cannot convert/parse a CSV field. What happens if I apply predicates for `null`. I guess it should be covered properly by expression implementations.
