pyorc 0.9.0

Python module for reading and writing Apache ORC file format.

PyORC

Python module for reading and writing Apache ORC file format. It uses the Apache ORC’s Core C++ API under the hood, and provides a similar interface as the csv module in the Python standard library.

Supports only Python 3.8 or newer and ORC 1.7.

Features

• Reading ORC files.

• Writing ORC files.

• While using Python’s stream/file-like object IO interface.

That sums up quite well the purpose of this project.

Example

Minimal example for reading an ORC file:

import pyorc

with open("./data.orc", "rb") as data:
    reader = pyorc.Reader(data)
    for row in reader:
        print(row)

And another for writing one:

import pyorc

with open("./new_data.orc", "wb") as data:
    with pyorc.Writer(data, "struct<col0:int,col1:string>") as writer:
        writer.write((1, "ORC from Python"))
