> ARROW-14612 changes the return value of the {{dictionaries}} attribute from None to a list in case some of the partitioning schema fields are not dictionary encoded. 
> But this can result in a non-clear mapping between arrays in {{Partitioning.dictionaries}} and fields in {{Partitioning.schema}}
