alt Hacker NewsEvery time some production environment can be simplified, it is good news in my opinion. The ideal situation with Rails would be if there is a simple way to switch back to Redis, so that you can start simple, and as soon as you hit some fundamental issue with using SolidQueue (mostly scalability, I guess, in environments where the queue is truly stressed -- and you don't want to have a Postgres scalability problem because of your queue), you have a simple upgrade path. But I bet a lot of Rails apps don't have high volumes, and having to maintain two systems can be just more complexity.
the problem i see here is that we end up treating the background job/task processor as part of the production system (e.g. the server that responds to requests, in the case of a web application) instead of a separate standalone thing. rails doesn’t make this distinction clear enough. it’s okay to back your tasks processor with a pg database (e.g. river[0]) but, as you indirectly pointed out, it shouldn’t be the same as the production database. this is why redis was preferred anyways: it was a lightweight database for the task processor to store state, etc. there’s still great arguments in favor of this setup. from what i’ve seen so far, solidqueue doesn’t make this separation.
