“A generational leap”: How Trio unified payment analytics and cut storage by 88% with ClickHouse Cloud

Trio, a Brazilian fintech specializing in high-volume electronic payments, utilizes ClickHouse as its single source of truth for payment analytics, which aids in reconciliation, compliance reporting, and customer dashboards. Following its acquisition of PayBrokers in 2025, Trio faced the challenge of managing a vast stream of payment data, which led them to adopt ClickHouse for its speed and efficiency, reducing storage needs by 88%. The architecture involves a custom ETL solution using Redpanda and Airflow, allowing for precise data shaping and handling schema drift before ingestion into ClickHouse. This setup supports real-time analytics and reconciliation through a sliding window approach, addressing late, duplicate, and out-of-order events without extensive recomputations. The transition to ClickHouse has significantly enhanced operational efficiency, enabling tighter feedback loops and easier data management. Trio's future plans include refining their architecture to further streamline operations and leverage new ClickHouse features to maintain a robust, scalable analytical foundation.
