I think ti won't.
I don't expect Koschei would use much more Koji resources than it already does. Koschei maintains a priority queue of package rebuilds and submits scratch builds as available Koji resources allow. The queue is almost never empty - there are almost always some packages to rebuild. An increased number of tracked packages would simply grow the queue, but would not lead to submitting much more scratch builds. IOW, packages would simply be rebuilt less often. To submit more scratch builds we would need larger builder capacity. This doesn't necessarily mean more or better hardware. Better Koji configuration would help a lot. We have some very powerful builders with up to 224 processors, but their capacity is set to 2. This means that the builder stops accepting new tasks once load gets to 2, which is less than 1 %. Example buildhw-a64-20.iad2.fedoraproject.org Capacity is 2, check with: koji hostinfo buildhw-a64-20.iad2.fedoraproject.org 224 CPUs, load average: 2.04, 2.07, 2.05 memory: 251Gi total, 7.3Gi used, 242Gi available Yet, at the time of writing the builder is marked as not ready (!!) for taking more builds due to exceeded capacity. This is not an individual case, we have many builders like that. Making all packages as tracked without increasing Koji builder capacity will limit Koschei usefulness for packagers that care about Koschei enough to manually opt-in. > 2) One-time enablement of all existing packages > > That should be doable.

I can implement points 2 and 3 easily, as long as there is consensus to do so. -- Mikolaj Izdebski > > > Can we do this?
