When analytics workloads start outgrowing their infrastructure, businesses often face a tough decision: migrate to a more powerful database or risk bottlenecks that slow everything down. One of our U.S. customers faced this exact challenge. They knew open source ClickHouse® was the future of their analytics – but the path to get there seemed daunting.
This is the story of how Quantrail stepped in, took ownership of the transition, and delivered a faster, leaner, and future-ready system – while the customer stayed focused on their business.
Customer Pain Points
The customer’s setup looked solid on the surface:
- A 70+ node Hadoop and Elasticsearch cluster powering critical analytics
- Multiple data pipelines feeding real-time business operations
- Complex reporting requirements with zero room for downtime
But underneath, challenges were building up:
- Infrastructure costs were spiraling
- Engineers were consumed with maintenance, not innovation
- Migration plans projected 6+ months of disruption
The desire to move to open source ClickHouse® was strong. The resources and time to do it alone? Not so much.
How Quantrail Got Into Action
From the very first discovery call, the Quantrail team made one thing clear:
“Open source ClickHouse® is our problem. Growth is yours.”
We mapped out and executed the entire journey – end-to-end, so the customer never had to lose focus on their core work.

- Migration Strategy – A no-risk roadmap for moving 70+ nodes into a leaner, high-performance ClickHouse® setup.
- Execution – Hands-free delivery of installation, schema migration, indexing, optimizations, query benchmarking, cluster topology, and monitoring.
- Optimization & Automation – Over 50 Airflow DAGs replaced fragile weekend batch jobs, every query was tuned, and every pipeline hardened.
- Production-Grade Reliability – HA, DR, and enterprise security baked in from day one.
- Robust Documentation – Every step tracked in Confluence, SQL queries version-controlled in Git.
- Training & Knowledge Transfer – Customized sessions equipped the customer’s team to manage and extend the new setup.

- Fuss-Free Migration – completed in just 4 months, cutting 2 months off their own projections and ensuring minimal disruption.
- Automation-First Reporting – brittle weekend jobs replaced with 50+ resilient Airflow DAGs.
- Future-Ready Architecture – engineered and load-tested for 12x ingestion growth.
