How to build DataFusion python wheel

[mmuru]

The latest python datafusion release 0.2.0 (from PyPi) was Dec 9, 2020. The DataFusion 4.0.0 version released but no official DataFusion release for Python. I am trying to build a wheel from the source but no setup.py or instructions how to build a wheel package. Please, can someone provide the steps or instructions how to build a wheel package? Thanks.

We will hopefully be able to release 0.3.0 this week. In the mean time you can follow the instructions at https://github.com/apache/arrow-datafusion/tree/master/python#how-to-develop. maturin is the command you want to use. maturin develop to build and install the binding into local python virtualenv. maturin release to build a release wheel that can be published to pypi index.
