> Our current doc does not explain we are passing the data source specific options to the
underlying data source:
> - https://spark.apache.org/docs/latest/sql-programming-guide.html#manually-specifying-options
> We can add some introduction section for both Parquet/ORC examples there. We had better
give both read/write side configuration examples, too. One example candidate is `dictionary
encoding`: `parquet.enable.dictionary` and `orc.dictionary.key.threshold` et al.
