pandas.read_orc — pandas 2.3.1 documentation

pandas.read_orc(path, columns=None, dtype_backend=<no_default>, filesystem=None, **kwargs)[source]#

Load an ORC object from the file path, returning a DataFrame.

Parameters:

pathstr, path object, or file-like object

String, path object (implementing os.PathLike[str]), or file-like object implementing a binary read() function. The string could be a URL. Valid URL schemes include http, ftp, s3, and file. For file URLs, a host is expected. A local file could be: file://localhost/path/to/table.orc.

columnslist, default None

If not None, only these columns will be read from the file. Output always follows the ordering of the file and not the columns list. This mirrors the original behaviour of pyarrow.orc.ORCFile.read().

dtype_backend{‘numpy_nullable’, ‘pyarrow’}, default ‘numpy_nullable’

Back-end data type applied to the resultant DataFrame (still experimental). Behaviour is as follows:

• "numpy_nullable": returns nullable-dtype-backed DataFrame (default).

• "pyarrow": returns pyarrow-backed nullable ArrowDtype DataFrame.

Added in version 2.0.

filesystemfsspec or pyarrow filesystem, default None

Filesystem object to use when reading the parquet file.

Added in version 2.1.0.

**kwargs

Any additional kwargs are passed to pyarrow.

Returns:

DataFrame

Notes

Before using this function you should read the user guide about ORC and install optional dependencies.

If path is a URI scheme pointing to a local or remote file (e.g. “s3://”), a pyarrow.fs filesystem will be attempted to read the file. You can also pass a pyarrow or fsspec filesystem object into the filesystem keyword to override this behavior.

Examples

>>> result = pd.read_orc("example_pa.orc")
