Travis Brady created ARROW-2459:
-----------------------------------
Summary: pyarrow: Segfault with pyarrow.deserialize_pandas
Key: ARROW-2459
URL: https://issues.apache.org/jira/browse/ARROW-2459
Project: Apache Arrow
Issue Type: Bug
Components: Python
Environment: OS X, Linux
Reporter: Travis Brady
Following up from [https://github.com/apache/arrow/issues/1884] wherein I found
that calling deserialize_pandas in the linked app.py script in the repo linked
below causes the app.py process to segfault.
I initially observed this on OS X, but have since confirmed that the behavior
exists on Linux as well.
Repo containing example: [https://github.com/travisbrady/sanic-arrow]
And more generally: what is the right way to get a Java-based HTTP microservice
to talk to a Python-based HTTP microservice using Arrow as the serialization
format? I'm exchanging DataFrame type objects (they are pandas.DataFrame's on
the Python side) between the two services for real-time scoring in a few
xgboost models implemented in Python.
