             Summary: [Python] Add path/URI /+ filesystem handling to parquet.read_metadata
                 Key: ARROW-16719
                 URL: https://issues.apache.org/jira/browse/ARROW-16719
             Project: Apache Arrow
          Issue Type: Improvement
          Components: Python
            Reporter: Joris Van den Bossche


Currently you can pass a local file path or file-like object, or a URI (eg "s3://...") or path+filesystem combo to {{parquet.read_table}}. 
But the {{parquet.read_metadata}} and {{parquet.read_schema}} methods (being a small wrapper around {{ParquetFile}} only accept the local file path or file-like object. I would propose to add the same path+filesystem handling to those functions as happens in {{read_table}} to make the capabilities of those consistent.

(I ran into this in geopandas, where we use {{read_table}} to read the actual data, but also need {{read_metadata}} to inspect the actual Parquet FileMetaData for metadata)
