Avoiding Redis Crashes with BullMQ: Memory Monitoring Basics
If you’re using BullMQ with Redis in production, you’ve probably dealt with a “wtf happened” moment after Redis hit its memory limit. 🧨😐 We hit this once (on a Sunday, naturally). Since then, we started tracking Redis memory usage per instance and get notified when we hit ~80% of capacity. 💡 Turns out some Redis […]
How We Handle BullMQ Queue Backlogs (Without Stressing Over It)
One of the most overlooked issues when working with BullMQ (or any job queue, really) is quietly building backlogs. It doesn’t crash the system – but it slows things down until something breaks. After a few rough incidents (hello weekend alerts 😅), we started tracking how many jobs are waiting, prioritized, or delayed per queue. […]
BullMQ UI: Why Bull Board May Not Be Enough (And How Upqueue.io Helps)
When your queue looks “quiet,” it might actually be failing silently TL;DR If you’re running BullMQ in production, you’ve likely got jobs, workers, and retries configured. But all the functionality in the world won’t help if you can’t see what’s actually happening. That’s where a true BullMQ UI becomes essential. A Good BullMQ UI Should […]
🐂 A Practical Guide to BullMQ in Node.js (With Observability Tips)
If you’ve ever needed to handle background jobs or async tasks in Node.js, you’ve likely run into tools like Bull, Agenda, or Kue. But these days, BullMQ is the go-to solution for serious queue management in modern Node environments — built on top of Redis with support for repeatable jobs, concurrency, retries, events, and more. […]
Using BullMQ to Power AI Workflows (with Observability in Mind)
As AI-based applications become more sophisticated, managing their asynchronous tasks becomes increasingly complex. Whether you’re generating content, processing embeddings, or chaining together multiple model calls – queues are essential infrastructure. And for many Node.js applications, BullMQ has become the go-to queueing library. In this post, we’ll walk through why BullMQ fits well into AI pipelines, and how […]
The Hidden Cost of Silent Queue Failures (And How We Learned the Hard Way)
A few months ago, we noticed something strange. Some background: we were relying heavily on BullMQ to power background job processing for parts of our backend infrastructure. It was working great – until it wasn’t. At first, the failures were subtle. A webhook wouldn’t fire. A report wouldn’t generate. A user would write in saying […]
Why Your Queue is Quiet? (But Not Healthy)
If you’ve worked with Redis-based queues like BullMQ, you’ve probably had this moment: Everything looks fine. And yet… A customer reports they never got their email. Or your nightly job didn’t run. Or a report didn’t get generated. And the worst part? You didn’t know anything was wrong. Common Queue Pitfalls (That No One Tells You About) […]
