Building a fault-tolerant metrics storage system at Airbnb How we built a storage system that ingests 50 million samples per second and stores 2.5 petabytes of logical time series data. By: Rishabh Kumar Modern observability practice encourages instrumenting every meaningful code path. Over the past 15 years, open-source observability SDKs like Prometheus, OpenTelemetry, and StatsD have made deep ...
This article presents a detailed case study of Airbnb’s transition to an internally operated metrics storage system, highlighting the engineering challenges and solutions involved in scaling observability infrastructure. The strongest version of this narrative emphasizes the technical sophistication required to handle massive data volumes while maintaining reliability and fault tolerance. The use of shuffle sharding, multi-cluster architecture, and automation reflects a mature approach to distri...
