How does PyArrow cope with multiprocessing.Manager? I remember there were
some inefficiencies when Pickle was used (mostly related to slicing) but
that in theory it should work.
That is probably an easy enough replacement for Plasma and is standard.

I mean, I doubt the plan is to disable jira before we can actually ship PRs
from github issues and thus block development.

To be honest I find this YAML based representation a bit confusing due to
the unclear parameters of functions.
In your specific example you have a JOIN taking two sources as their
inputs.
But how do I know that the two sources are meant to be inputs to the join?
And not only that the last source is

There are multiple reasons why exposing Arrow to end users instead of
restricting it to developers of framework would be beneficial for the Arrow

I recently noticed that in the Java implementation we expose a set/setSafe

While working on https://github.com/apache/arrow/pull/10162 it was raised
the concern that it's hard to change Cython code because it might break
third party libraries and projects relying on pyarrow through Cython.
Mostly the problem comes from the fact that the documentation suggests

As Arrow/PyArrow grows more compute functions and features we might move
toward a world where the number of users relying on PyArrow without going
through Pandas or NumPy might grow.
NumPy is a compile time dependency for PyArrow as it's required to compile
the C++ code needed to implement the pan
PyArrow is currently full Cython codebase, but in reality it relies on some
classes and functions that are implemented in C++ within the src/python

I guess that doing it at the Parquet reader level might allow the

Hi,
I'd like to share with the ML an idea which me and Nic Crane have been
experimenting with. It's still in the early stage, but we hope to turn it
into a PR for Arrow documentation soon.
The idea is to work on a Cookbook, a collection of ready made recipes, on
how to use Arrow that both end use
Another approach that could reduce the amount of heavy tests that we have
to write (if the tests are written in Python) might be to drive the code to
interleave in the ways we feel might introduce problems. Such an approach
can be performed by introducing explicit breakpoints in the code and

Hi Radu,
I was trying to reproduce the issue you described, but I was unable to
reproduce the problem.
Could you provide an example of how you built the Table?
I tried reproducing it with a table with following schema

Are you sure you haven't installed `libarrow` (the CPP one) manually
independently from pyarrow?
In your traceback you have that the symbol has not been found in
"/usr/local/lib/libarrow.400.dylib"
But that smells like an independently installed libarrow, as the libarrow
provided by pyarrow shoul
Would "incorporate" mean that the codebase is moved into the arrow
repository or is the plan to keep a separate repository
for datafusion-python but under the apache org?
