    Rewrite the given partitionFilters to be used for filtering partition values.

    Rewrite the given partitionFilters to be used for filtering partition values. We need to explicitly resolve the partitioning columns here because the partition columns are stored as keys of a Map type instead of attributes in the AddFile schema (below) and thus cannot be resolved automatically.

    partitionFilters
