Wes McKinney created ARROW-8998:
-----------------------------------
Summary: [Python] Make NumPy an optional runtime dependency
Key: ARROW-8998
URL: https://issues.apache.org/jira/browse/ARROW-8998
Project: Apache Arrow
Issue Type: New Feature
Components: Python
Reporter: Wes McKinney
Since in the relatively near future, one will be able to do non-trivial
analytical operations and query processing natively on Arrow data structures
through pyarrow, it does not make sense to require users to always install
NumPy when that install pyarrow. I propose to split the NumPy-depending parts
of libarrow_python into a libarrow_numpy (which also must be bundled) and
moving this part of the codebase into a separate Cython module.
This refactoring should be relatively painless though there may be a number of
packaging details to chase up since this would introduce a new shared library
to be installed in various packaging targets.
