[jira] [Created] (ARROW-1096) [C++] Memory mapping file over 4GB
fails on Windows
Wes McKinney created ARROW-1096:
-----------------------------------
Summary: [C++] Memory mapping file over 4GB fails on Windows
Key: ARROW-1096
URL: https://issues.apache.org/jira/browse/ARROW-1096
Project: Apache Arrow
Issue Type: Bug
Components: C++, Python
Affects Versions: 0.4.0
Reporter: Wes McKinney
This succeeds on a 3.4 GB file, but fails on a 6GB file. I suspect the failure point is exactly 4GB but will investigate
{code}
In [9]: mm = pyarrow.memory_map('df_big.feather')
