hi Rok, I would guess that GitHub Actions will have the same resource and hardware limitations that Travis CI and Appveyor currently have, as well as organization-level resource contention with the rest of the ASF.
We need to have dedicated, powerful hardware (more cores, more RAM), with more capabilities (architectures other than x86, and with GPUs), that can run jobs longer than 50 minutes, with the ability to scale up as the project grows in # of contributions per month. In the past month Arrow had 4300 hours of builds on Travis CI. What will happen when we need 10,000 or more hours per month to verify all of our patches? At the current rapid rate of project growth it is only a matter of time. I made a graph of commits to master by month: https://imgur.com/a/02TtGXx With nearly ~300 commits in the month of June alone, it begs the question how to support 500 commits per month, or 1000. - Wes On Sat, Jun 29, 2019 at 5:19 AM Rok Mihevc <rok.mih...@gmail.com> wrote: > > GitHub Actions are currently in limited public beta and appear to be > similar to GitLab CI: https://github.com/features/actions > More here: https://help.github.com/en/articles/about-github-actions > > Rok > > On Fri, Jun 28, 2019 at 7:06 PM Wes McKinney <wesmck...@gmail.com> wrote: > > > Based on the discussion in > > https://issues.apache.org/jira/browse/INFRA-18533 it does not appear > > to be ASF Infra's inclination to allow projects to donate money to the > > Foundation to get more build resources on Travis CI.
