Why "just retry" creates duplicate payments, and a PostgreSQL-backed design for idempotency keys that survives double clicks, timeouts, crashes and…
Quick Answer: A retry storm occurs when deeply nested microservices independently retry failed downstream requests, causing exponential traffic ampl…
In short: When the same data is edited on several devices, "keep the newest" is unreliable, because device clocks disagree and messages arrive late.…
Why Industrial Edge Gateways Need Store-and-Forward Many teams still treat an industrial edge gateway as a simple protocol bridge: collect data from…
Work on a distributed system long enough and you'll know the particular cold sweat of the dual write. You insert an order into the database and the…
The signal problem I was trying to understand how mature systems separate signal from noise when many alerts arrive at once. I had been working thro…
Most AI agent frameworks focus on orchestration, prompts, and tool calling. But as autonomous agents gain authority to act in the real world (trigge…
A few days ago, I picked up the new edition of Designing Data-Intensive Applications by Martin Kleppmann . I'm still in Chapter 1. The book has been…
Today I want to talk about split-brain. The name sounds dramatic, and the problem is dramatic too. One system splits into two halves, and each half…
I run an automated trading system on a paper account. Two pipelines, a handful of small single-purpose agents, no human in the loop once it starts.…
Building backend systems for fintech is fundamentally different from almost any other domain. The stakes are absolute, the edge cases are catastroph…
If someone asks you to explain Raft, you might hear a list of terms like: Leader election Terms RequestVote AppendEntries Log replication Commit ind…

In the previous part of this series, we built a Publish / Subscribe Broker from scratch. We saw how a central coordinator could fan out events acros…
Most of the event-driven architecture I've built started the same way: a synchronous call chain that worked fine in a demo and fell over under real…
Here is the event order I use as a paper counterexample when someone treats a free sandbox as durable storage. The planner sends apply_patch , the s…
In distributed systems, the Transactional Outbox Pattern is a common way to reliably publish events after a database transaction. The idea is simple…
Circuit Breaker Pattern What happens when one service fails, but your entire system keeps calling it anyway ? Imagine your payment service is down.…

One-liner: A distributed lock ensures that only one node in a cluster can perform a critical operation at a time — preventing race conditions across…
There's a line of code in almost every service that stores replicated data: def resolve ( incoming , stored ): # keep whichever write is "newer" ret…
One-liner: A circuit breaker stops calling a failing service to give it time to recover — instead of hammering it with requests that are guaranteed…
Building Faultline: A Reusable Chaos-Injection and Linearizability-Checking Harness Faultline is an open-source Go harness that injects faults into…
Retries keep distributed systems moving through timeouts and temporary failures. In an access system, though, an old retry can be more dangerous tha…

Hello, DEV 👋 After spending years working in Site Reliability and Platform Engineering , I figured it was finally time to start writing about the th…
During an incremental system migration, I ran into a subtle consistency problem: our new service could successfully update the database while the le…
