Concurrency Gating via Wait Steps

After having discovered Concurrency Gates - Buildkite Blog, via other topics in this community, it seems that all of the examples have a throwaway command step used for this purpose. However, since wait steps naturally act as “gates”, and because, without special configuration or use of plugins, throwaway command steps still incur a repository clone cost, wait seems a much more natural way to express concurrency gates in many cases.

Hi, @kgillette!

You wouldn’t be able to use a wait step to declare the gates as you can’t assign a concurrency group to a wait step, which is why we recommend using the command steps to open and close the gates.

Hopefully, that helps explain things a bit, but if you need more clarification please let us know :smile:

Right. That can’t be done right now, but I’m requesting that as a feature:

That the wait step get extended to have concurrency group attributes, and for one or more to act as a concurrency gate.

@kgillette sure thing! I’ll raise this as a feature request with our Product team.
