Jacob Wujciak-Jens commented on ARROW-16794:
--------------------------------------------
A less specific key would also mean fewer caches (global cache size is limited
per repo) -> fewer evictions -> fewer misses
> [CI][C++] MinGW builds sometimes time out
> -----------------------------------------

> Key: ARROW-16794
> URL: https://issues.apache.org/jira/browse/ARROW-16794
> Project: Apache Arrow
> Issue Type: Bug
> Components: C++, Continuous Integration
> Reporter: Antoine Pitrou

> When ccache is cold, the MinGW builds sometimes exceed the (large) 55 minutes
> timeout:
> https://github.com/apache/arrow/runs/6806190892?check_suite_focus=true
> C++ compile times have always been a concern on CI, but it may only grow as
> the codebase expands.
