I think the current issue is that the original PySpark can display complex
struct types,
```

Python 3.11.1 (v3.11.1:a7a450f84a, Dec 6 2022, 15:24:06) [Clang 13.0.0
(clang-1300.0.29.30)] on darwin
Type "help", "copyright", "credits" or "license" for more information.
Setting default log level to "WARN".
To adjust logging level use sc.setLogLevel(newLevel). For SparkR, use
setLogLevel(newLevel).

but PyConnect and Scala code cannot. Ultimately, we should make them
consistent. Should we consider removing the current capability of PySpark?
However, this might be a breaking change.
