Sharding high-throughput Redis without downtime

Every day, more and more software teams rely on Inngest for their core infrastructure which results in increased load on our core systems. When building distributed systems, vertical scaling can only get you so far. Because of that, we took on a project to horizontally scale by sharding our most crucial database, which serves more than 50,000 requests per second at low latency. As Inngest is critical infrastructure for many customers, we aim to avoid maintenance windows at all costs. In this post we’ll walk through how we sharded our function state database with zero downtime....Inngest, Systems Architecture, Redis, Sharding

Making Architects work in Software Teams

As teams grow, managers invariably start to think about dividing the former team into smaller groups working on specific features or areas, in most cases supported by people or small teams that focus on tooling, infrastructure, and other “meta” tasks that enable engineering....Engineering Management, Product Development

From regression to neural networks

While ML is all the rage right now, it is important to understand the fundamentals powering the incredible breakthroughs in fields like natural language processing (NLP), computer vision (CV), and generative AI in the past years....Neural Networks, Deep Learning

Steady State means Continuous Rewriting

Most software companies don’t ever get to see a steady state, where the core product has been built, the rate of innovation decreases, and maintenance and minor improvements become the primary workload. In this world, priorities shift from figuring out the product, to ensuring customers are happy and keeping the lights on....Engineering Management

Serializing Data between Systems with Anzu Values

This post goes over some of our architecture work for the first iteration of Anzu. We’re currently hard at work building the next big step to get closer to our vision of helping teams ship faster, so make sure to check this blog out for updates regularly. If you haven’t read the previous posts in this series, give them a shot....Systems Architecture, Anzu

Improving Local Development with Atlas

If you’ve worked on a product that depends on multiple services and surrounding cloud resources, you’ve probably wondered about the best way to set things up for local development. Most teams default to the good old Docker Compose setup supported by some scripts, and that works until you run into the limits of a static configuration....Systems Architecture, Infrastructure-as-Code (IaC)

Fundamental Design Decisions for Scalable Systems

When building customer-facing systems, especially in the realm of SaaS businesses, it's important to get a couple design aspects of your system right early on, if you want to plan at scale and grow without unexpected side effects....Evergreen, Systems Architecture, Engineering Management

Looking back on a decade in software engineering

I can’t say for sure whether it was late 2012 or early 2013 but around that time I probably wrote my first, very scrappy, lines of code. Back then it didn’t dawn on me that I was about to embark on a career path that would open up so many experiences down the road, I just wanted to build some extensions to a popular Java-based video game (ten points if you can guess it) I routinely played with my friends at the time....Startups, Personal

What's Next

I’ve always enjoyed building software and solving problems. Back in 2012, I started hacking around with Java to build Minecraft plugins for me and my friends to enjoy. It took way longer than I’d like to admit until I got the first version running successfully, and I absolutely did not know what I was doing, but it felt rewarding enough, and so I kept going....Personal

A primer on SSO with SAML

Implementing features like Single Sign-On (SSO) usually is one of the loathed tasks when building a SaaS product. Bigger customers, especially in the enterprise segment, will require integration with their identity providers like Azure AD or Okta, allowing them to sign in with their existing company account....Single Sign-On (SSO), SAML, Node.js
