Post by RudderStack

bol is the largest eCommerce platform in the Netherlands and Belgium, serving 13 million customers and 50,000+ retail partners. They process more than one billion customer events every day. At that scale, even brief outages can cost hundreds of thousands of euros, and their in-house infrastructure was no longer holding up. Event schemas were loosely defined, owned by no one, and broken events could go undetected for weeks. Rather than committing to a costly internal rebuild, they evaluated customer data infrastructure platforms built for the AI era. With RudderStack, they replaced that technical debt with a governed, scalable data foundation: → Reliable event streaming, tested at 150,000 events per second without data loss → Tracking plans versioned and validated via the RudderStack CLI → GitLab CI pipelines automating schema checks across staging and production → Real-time observability and automated alerting As Koen L., Senior Engineering Manager at bol.com, put it: "We use RudderStack as if it's part of our own team. From load testing to transformation isolation, they've been all-in on building the right platform with us." One billion events a day. The data just works. Get the full story in the comments ⬇️
