> > `closer.lua` redirects to dlcdn.apache.org or something for the latest release and archive.apache.org for old releases automatically. > > If we use `closer.lua`, then downloads risk failing again when the `closer.lua` service is unavailable, right? The point of a CDN is to make the downloads reliable. Right. But I think that `closer.lua` is enough stable. I've never seen `closer`.lua` down. > https://dlcdn.apache.org/orc/ provides several older ORC releases, and we should bump to the newer version regularly anyway. It works for the latest Apache Arrow release. If a user wants to build old Apache Arrow, the target ORC may not exist in https://dlcdn.apache.org/orc/ . For example, Apache Arrow 16.0.0 uses ORC 2.0.0 https://github.com/apache/arrow/blob/apache-arrow-16.0.0/cpp/thirdparty/versions.txt#L93 but ORC 2.0.0 doesn't exist in https://dlcdn.apache.org/orc/ now. `closer.lua` always works both for ORC 2.0.3 and ORC 2.0.0. -- This is an automated message from the Apache Git Service.
