--------------------------------
Summary: Cython API does not mirror all C++ functions
Key: ARROW-13335
URL: https://issues.apache.org/jira/browse/ARROW-13335
Project: Apache Arrow
Issue Type: Improvement
Components: Python
Reporter: syntonym
Attachments: arrow_test.pyx, setup3.py
I have some data in a pyarrow table and am running an algorithm on it which can
not be (efficiently) expressed as a combination of pyarrow compute function
calls. I used cython to implement the algorithm, but it seems that not the
entire C++ API is exposed in cython, e.g. in
python/pyarrow/includes/libarrow.pxd:1049 all ArrayBuilders lack the
UnsafeAppend method. The documentation states `The Cython API more or less
mirrors the C++ API` which I guess could mean that some methods are not
available, but using UnsafeAppend seems like a good reason to use cython.
Or maybe I just inlcuded headers wrong/I shouldn't bind against these cython
headers but directly against the c++ or something? I attached a code example
with a setup.py in case I did that incorrectly.
