LINE MANGA solved real-time analytics challenges by using ClickHouse to query their existing MySQL databases directly, without data migration. Their approach uses ClickHouse's MySQL Table Engine and Database Engine to create virtual tables that reference MySQL instances, enabling complex joins across horizontally sharded data. The solution allows real-time analysis of user behavior and sales data while maintaining MySQL as the system of record, with condition pushdown optimizing performance by filtering data at the source.
