When introducing parallelism in Rails,
the real danger isn’t threads.

It’s connection pool exhaustion.

Based on a Kaigi on Rails 2025 talk by @katakyo, I wrote a breakdown of how to safely scale parallel workloads in production Rails systems.

Is there a tool to track Github issue activity (comments, 👍 reactions, external issues referencing the initial issue)? Comments are good, but I think seeing an increase in reactions or issues referencing it would be helpful too.
Prioritizing few hundreds issues is hard.

♻️ Sometimes I find it hard to revisit earlier team ideas. It can feel like recycling old solutions, like adding calendar slots for PR reviews, increasing the number of daily meetings, or introducing more process before building a PoC.
We already tried these approaches and they failed, but a year later they come back, and you already know they won’t work.

How do you balance the urge to contribute more to OSS with slow reviews/merges and the stress of pending PRs? It’s overwhelming when work stalls and users are impacted.

I value fast, thorough reviews and quick releases. I want to avoid lingering “in‑between” work that creates stress and unfinished tasks.

No criticism of maintainers with day jobs. I just dream of an OSS project used at work, backed by a company, with fast reviews and merges.
