> [Python] Refine pyarrow.parquet API exposure
> --------------------------------------------
>
>                 Key: ARROW-17320
>                 URL: https://issues.apache.org/jira/browse/ARROW-17320
>             Project: Apache Arrow
>          Issue Type: Improvement
>          Components: Parquet, Python
>            Reporter: Miles Granger
>            Priority: Major
>
> Spawning from 
> [ARROW-17106|https://issues.apache.org/jira/browse/ARROW-17106], moving code 
> from `pyarrow/parquet/__init__` to `pyarrow/parquet/core` and re-exporting in 
> `__init__` to maintain the same functionality.
> [pyarrow.__init__|https://github.com/apache/arrow/blob/master/python/pyarrow/__init__.py]
>  is very careful about what is exposed through the public API by prefixing 
> private symbols with underscores, even imports. 
> What's exposed at the top level of `{{{}pyarrow.parquet{}}}`, however, is not 
> so careful. API calls such as `{{{}pq.FileSystem{}}}`, `{{{}pq.pa.Array{}}}`, 
> `{{{}pq.json{}}}` are all valid and should probably be designated as private 
> attributes in {{{}pyarrow.parquet{}}}.
