O11y in One: ClickHouse as a Unified Telemetry Database Link to heading
OpenTelemetry is often introduced as a way to send your metrics, traces, and logs to separate backend databases. But in reality, most organizations juggle at least half a dozen monitoring tools in production. What we really need isn’t just a standardized way to collect telemetry—it’s a unified datastore that brings all the backends together, much like how OpenTelemetry has a unified telemetry collection. Could ClickHouse be that solution? In this talk, Joshua will dive into the fundamental nature of telemetry and explore what we truly need from a unified telemetry datastore. He’ll break down the specific features of ClickHouse that make it an exceptional choice for tracing and logs today—and hint at its growing potential for time-series data in the future. From there, he’ll highlight the seamless integrations between ClickHouse and open-source tools like OpenTelemetry, Prometheus, Grafana, and Kafka, showcasing how these technologies work together to enhance observability pipelines. Finally, we’ll take a closer look at cutting-edge, open-source observability platforms built on ClickHouse, including CoRoot, QRYN, and SigNoz. Whether you’re building a complete observability platform or exploring how to simplify your own observability strategy, this session will equip you with insights into leveraging ClickHouse as a core part of your telemetry infrastructure. Join us to learn how to move beyond fragmented tools and unlock the power of unified observability.
