Load a parquet object from the file path, returning a DataFrame.
Any valid string path is acceptable. The string could be a URL. Valid
URL schemes include http, ftp, s3, gs, and file. For file URLs, a host is
expected. A local file could be:
A file URL can also be a path to a directory that contains multiple
partitioned parquet files. Both pyarrow and fastparquet support
paths to directories as well as file URLs. A directory path could be:
file://localhost/path/to/tables or s3://bucket/partition_dir
If you want to pass in a path object, pandas accepts any
By file-like object, we refer to objects with a read() method,
such as a file handle (e.g. via builtin open function)
Parquet library to use. If ‘auto’, then the option
io.parquet.engine is used. The default io.parquet.engine
behavior is to try ‘pyarrow’, falling back to ‘fastparquet’ if
‘pyarrow’ is unavailable.
If not None, only these columns will be read from the file.
If True, use dtypes that use pd.NA as missing value indicator
for the resulting DataFrame (only applicable for engine="pyarrow").
As new dtypes are added that support pd.NA in the future, the
output with this option will change to use those dtypes.
Note: this is an experimental option, and behaviour (e.g. additional
support dtypes) may change without notice.
New in version 1.2.0.
Any additional kwargs are passed to the engine.
