How ClickHouse Cloud enabled LaunchDarkly to build and ship features faster

LaunchDarkly has transitioned to using ClickHouse Cloud to manage its data architecture, significantly improving its ability to process high-cardinality data at scale and reducing data latency to seconds. This shift has allowed LaunchDarkly to move away from expensive and maintenance-heavy streaming pipelines and batch warehouses, enabling faster feature development and unlocking new product capabilities. The adoption of ClickHouse has simplified the data infrastructure, allowing for direct querying of raw data and reducing the need for bespoke ETL jobs. This has led to a more efficient system, providing LaunchDarkly with the ability to store, query, and correlate feature flag evaluations, product analytics, and observability signals, which enhances their ability to deliver richer analytics and data-driven product features. The flexibility and performance of ClickHouse have allowed LaunchDarkly to consolidate its data systems, paving the way for new initiatives such as Release Guardian, which aims to automate reactions to software releases by connecting feature evaluations with performance metrics. The transition has also fostered a more unified approach to data across the organization, reducing architectural complexity and increasing the velocity of feature delivery.
