LINEマンガがClickHouseを使用し、 データを1行も取り込まずにリアルタイム分析が可能なシステムを実現

LINE Digital Frontier, a subsidiary of WEBTOON Entertainment, manages LINE Manga, a leading digital comic platform with around 150 million monthly active users, leveraging data analytics to optimize recommendations and sales tracking. Despite its success, the platform faced challenges with its extensive MySQL database network, which hindered large-scale data analysis due to complex and time-consuming processes. To address this, LINE Manga integrated ClickHouse, enabling real-time querying of MySQL without data ingestion, thus improving efficiency by directly querying MySQL with virtual tables. This method allows seamless integration of product and user transaction data from different servers, supporting real-time SQL responses. The use of ClickHouse has streamlined operations, making query execution significantly faster and easier to debug while maintaining MySQL as the primary record system. The solution serves as a model for other developers, showcasing how to enhance data processing without overhauling existing systems.
