Antoine Pitrou created ARROW-16335:
--------------------------------------
Summary: [Release][C++] Windows source verification runs C++ tests
on a single thread
Key: ARROW-16335
URL: https://issues.apache.org/jira/browse/ARROW-16335
Project: Apache Arrow
Issue Type: Improvement
Components: C++, Developer Tools
Reporter: Antoine Pitrou
Fix For: 9.0.0
{{verify-release-candidate.bat}} uses the following command to run the C++
tests:
{code}
ctest -VV
{code}
This has two problems:
* output is verbose even for successful tests, making it difficult to find
errors in the log
* tests are run serially even on a many-core machine
I would suggest instead something like:
{code}
ctest -jN --output-on-failure
{code}
(where N is the available number of hardware threads / CPU cores)
