Francis, thanks for raising this up. +1 for disabling AppVeyor
I think we should need to keep Travis around for a while to evaluate how GitHub Actions work. Frankly speaking, I find Travis logs more responsive and a bit easier to see at the moment (e.g. they are colored, etc, etc). >integration in Avatica fails on every commit because the appvoyer.yml >was removed. I tried to keep Appveyor for Calcite, and in practice the queueing time there is extremely high. It can easily be Travis: ok, Actions: ok, AppVeyor: queued :-/ Vladimir
