毎秒100万イベント: LagoがClickHouse Cloudで使用量ベースの課金をスケールさせる方法

Lago leverages ClickHouse Cloud to handle real-time usage-based billing and complex monetization for large enterprises, scaling from 10,000 to 1,000,000 events per second. Initially a startup, Lago founders realized the critical nature of billing infrastructure while working at fintech company Qonto, where billing complexities rapidly escalated. Aiming to transform the approach to billing, Lago emphasizes open-source solutions that are transparent and adaptable, contrasting with the inflexible models of many billing vendors. As Lago's platform matured, it attracted larger and more demanding enterprises like PayPal, necessitating a robust data infrastructure to support massive usage events. After evaluating several database solutions, Lago chose ClickHouse for its performance and ease of understanding, integrating it with their existing pipelines using ClickPipes. ClickHouse now underpins Lago's billing engine, supporting high-speed ingestion, analysis, and activity logging. As Lago continues to serve larger organizations, ClickHouse plays a crucial role in maintaining performance and reliability, with future plans to consolidate more workloads onto this platform for streamlined operations.
