------------------------------------------
Summary: Downloading sources of pyarrow and its requirements from
pypi takes several minutes starting from 0.16.0
Key: ARROW-8983
URL: https://issues.apache.org/jira/browse/ARROW-8983
Project: Apache Arrow
Issue Type: Bug
Affects Versions: 0.17.1, 0.17.0, 0.16.0
Reporter: Valentyn Tymofieiev
It appears that
python -m pip download --dest /tmp pyarrow==0.17.1 --no-binary :all:
takes several minutes to execute.
There seems to be an increase in runtime starting from 0.16.0: on Python 2
python -m pip download --dest /tmp pyarrow==0.15.1 --no-binary :all:
appears to be somewhat faster, but the same command is still slow on Py3.
The command is stuck for a while with "Installing build dependencies ... ", and
increased CPU usage.
The intent of this command is to download source tarball for a package and its
dependencies.
Some investigation was started on the mailing list:
