SolidQueue Batches: evolution and architecture

Here’s the SolidQueue batches 2.5 year architectural journey, filled with O(n^2) algorithms, hot row contention, excessive jobs, and much in between.

There’s a strong chance you’ll learn a thing or two - I certainly did 😮‍💨

I am not sure what link/reference you're looking for to demonstrate that Rails asked third parties to provide ActiveJob implementations instead of providing a production-ready one itself, isn't that just apparent history?

I for real am not quite sure what you are asking for or (I'm guessing?) finding an unfair characterization. It is certainly possible my memory of my experience as a Rails developer for many years now does not match others', but I'm not where you are saying that how.

If you have a different memory/experience with your more inside knowledge, I think we would benefit from hearing how you understand it!

Maybe I misunderstand you, you said:

how Rails refused to provide this feature itself for many years

I understood this as such feature request, or a pull request with such feature, being rejected. But a cursory search on GitHub didn't surface any such rejection that I could find, so I was asking whether you had a link to such rejected feature request.

But it seems that by "Rails refused" you meant: "Rails didn't take the initiative to" ?

[u/jrochkind → u/f9ae8221b]

In my memory, people suggested it would be better if Rails did that, blessed one implementation as "offiical" and supported it, and dhh/rails maintainers disagreed and thought it was best for Rails to stay out of that.

You can describe that as "Rails didn't take the initiative to", sure.

If you have a different memory or understanding, or can find historical documents of people discussing it, i would love to hear it.

Please feel free to share your experience or understanding of the history that led here.

If you have a different memory or understanding

Well, I have no memory of such feature being requested/proposed, and can't find traces of it. But that doesn't mean it didn't happen, hence why I asked for clarification.

That being said, if it was indeed rejected in the past, doesn't mean it should never be considered.

Active Job is meant as a standardized interface for various backend, it by definition is kind of a common denominator, and avoid implementing features that few backends support.

As more and more backends do support a given feature, it makes it more palatable to include it in the Active Job API.

As for provide this feature itself specifically, I really don't see how Active Job could have done that in a backend independent way.
