> Currently, there are still cases where a data type isn't supported as the
> Python data type will be firstly converted to TypeInformation which will lose
> a few information, e.g,
> - the precision for TimeType could only be 0
> - the length for VarBinaryType/VarCharType could only be 0x7fffffff
> - the precision/scale for DecimalType could only be 38/18
> - the precision for TimestampType/LocalZonedTimestampType could only be 3
> - the resolution for DayTimeIntervalType could only be `SECOND` and the
> fractionalPrecision could only be 3
> - the resolution for YearMonthIntervalType could only be `MONTH` and the
> `yearPrecision` could only be 2
> - the CharType/BinaryType/ZonedTimestampType is not supported
> We should throw exceptions for the cases not supported.
