arrow/python

Python library for Apache Arrow

This library provides a Pythonic API wrapper for the reference Arrow C++ implementation, along with tools for interoperability with pandas, NumPy, and other traditional Python scientific computing packages.

Development details

This project is layered in two pieces:

• pyarrow, a C++ library for easier interoperability between Arrow C++, NumPy, and pandas
• Cython extensions and pure Python code under arrow/ which expose Arrow C++ and pyarrow to pure Python users

PyArrow Dependencies:

These are the various projects that PyArrow depends on.

1. g++ and gcc Version >= 4.8
2. cmake > 2.8.6
3. boost
4. Parquet-cpp

The preferred way to install parquet-cpp is to use conda. You need to set the PARQUET_HOME environment variable to where parquet-cpp is installed.

conda install -y --channel apache/channel/dev parquet-cpp

5. Arrow-cpp and its dependencies*

   The Arrow C++ library must be built with all options enabled and installed with ARROW_HOME environment variable set to the installation location. Look at (https://github.com/apache/arrow/blob/master/cpp/README.md) for instructions. Alternatively you could just install arrow-cpp from conda.

conda install arrow-cpp -c apache/channel/dev

6. Python dependencies: numpy, pandas, cython, pytest

Install pyarrow

python setup.py build_ext --inplace
