-------------------------------------
Summary: 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
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{}}}.
