Case Study: Juspay achieves real-time payment analytics and 10x cost reduction with ClickHouse

Fintech Leader Juspay Analyzes Over 50 Million Daily Payment Transactions in Real-Time with ClickHouse

Juspay, an Indian fintech company, needed a way to monitor and analyze its end-to-end payment system at massive scale while supporting frequent daily releases. To power A/B testing, real-time monitoring, and merchant analytics, Juspay turned to ClickHouse and its high-performance data platform.

Using ClickHouse alongside Kafka and Grafana, Juspay was able to compare release performance across millions of transactions, roll back changes when success rates dropped, and give merchants real-time dashboards for transaction success and failure status. The move from BigQuery to ClickHouse delivered a 10x reduction in operating costs, while still supporting analysis of around 50 million daily transactions and roughly 4TB of test data over seven days.
