How Eisan made POS analytics faster, cheaper, and more reliable with ClickHouse Cloud

Eisan System Development has transitioned from a QlikView-based BI system to ClickHouse Cloud to enhance the reliability and performance of its real-time ID-POS analytics platform for retail clients, allowing for basket analysis, cross-analysis, and personalized recommendations. This change was driven by the growing data volumes and demands for real-time insights that the previous system could not efficiently handle, leading to high costs and unreliable performance. ClickHouse, discovered by Eisan during an exploration of open-source alternatives, provided a solution with its speed and predictable performance under pressure, even with lower hardware specifications. Eisan's journey with ClickHouse involves ongoing optimization, with plans to scale the system to handle up to 100 billion records by making smart architectural decisions and exploring efficient resource usage. The focus is not only on improving processing times but also on operational strategies to manage large-scale, real-time analytics systems effectively as data and user expectations grow.
