The code from this repository reflects the final state of the application built in my Build Python Extensions for Apache Arrow Data with nanoarrow on YouTube.

How to build

If you don't already have meson, be sure to install that first:

python -m pip install meson

You can then configure and build the project:

meson setup builddir && cd builddir
meson compile

Using the library

From the build folder, you can directly import the library and use it:

import pyarrow as pa

import pyarrow_ext

arr = pa.array([1, 2, 3])
pyarrow_ext.sum(arr)
