Antoine Pitrou updated ARROW-8012:
----------------------------------
Component/s: Continuous Integration
> [C++][CI] Set CTEST_PARALLEL_LEVEL to $concurrency
> --------------------------------------------------
>
> Key: ARROW-8012
> URL: https://issues.apache.org/jira/browse/ARROW-8012
> Project: Apache Arrow
> Issue Type: Improvement
> Components: C++, CI, Continuous Integration
> Affects Versions: 0.16.0
> Reporter: Ben Kietzman
> Priority: Major
>
> Currently the default {{test}} target runs serially while {{unittest}} arbitrarily uses 4 threads. On many systems that's suboptimal. The environment variable {{CTEST_PARALLEL_LEVEL}} can be set to run tests in parallel, and we should probably have a good default for it (like the hardware concurrency)
