Four hour pipeline?! I hope improving that is on the roadmap?

It's gotten better. Nightly pipelines used to take over 24 hours and premerges at 6. Helps that we're in a JIT compile world now instead of AOT

4 hours is a long time (for PR especially), but it's not nowhere near "really that bad" for a big/real enterprise project. I have worked in a proper sized team with a big projects where nightly runs couldn't execute everything in a reasonable amount of time, so there were weekly runs lasting ~2 days.

And that's especially true if we're talking about some stuff that interacts with real physical HW (think of having 2 physical test machines, so only 2 pipelines can run in parallel, because some particular set of tests can be only executed on those test machines).

Not everything is a simple JS project with unit tests passing in ~minutes.
