> Key: IMPALA-9999
> URL: https://issues.apache.org/jira/browse/IMPALA-9999
> Project: IMPALA
> Issue Type: Improvement
> Components: Backend, Infrastructure
> Affects Versions: Impala 4.0.0
> Reporter: Joe McDonnell
> Priority: Major
> Attachments: perf-AB-test-321-result.txt, perf-AB-test-322-result.txt
>
>
> Impala recently updated to use GCC 7.5. This got past the major ABI changes,
> so it makes sense to keep going and update to even more recent versions of
> GCC. This tracks the tasks necessary to switch to GCC 9.2 or above (which is
> already available in the toolchain).
