Beyond the warehouse: How METRO Markets built a do-it-all data platform on ClickHouse Cloud

METRO Markets leveraged ClickHouse Cloud to revolutionize their data infrastructure, consolidating all company data into a single warehouse for the first time in its history and achieving faster query performance and lower storage costs compared to BigQuery and Snowflake. This transition followed the limitations of their previous self-hosted Hadoop-based stack, which faced scaling and reliability issues as the company expanded. The adoption of ClickHouse has allowed METRO Markets to provide real-time seller analytics, credit risk modeling, and observability, while also enabling new AI applications, streamlining decision-making processes across their European operations. The implementation of ClickHouse has not only improved data accessibility and reliability, but it has also facilitated a unified view of data for different teams, enhancing strategic and operational efficiency. The company's data team, having previously struggled with maintaining the old infrastructure, now benefits from ClickHouse's managed solution, significantly reducing operational burdens and ensuring consistent data availability and speed. Looking forward, METRO Markets plans to further integrate their streaming infrastructure with ClickHouse to expand real-time processing capabilities, indicating an ongoing evolution of their data platform beyond its initial scope.
