> HUDI-5807 allows fg reader to read partition column values from the file
> instead of just using the directory path structure. HUDI-8036 stores the
> partition column keygen types.
> In HoodieHadoopFsRelationFactory, partitionColumnsToRead is set to the list
> of all partition columns if the keygen type is timestamp or custom keygen. In
> the case of custom keygen, filter that list to only the timestamp keygen
> columns.
