Case Study: Rakuten achieves 14x faster query performance and cloud analytics modernization with AtScale

Rakuten Speeds Data Queries and Avoids Business Interruptions with AtScale

Rakuten, a shopping rewards company serving over 13 million customers, faced growing analytics bottlenecks from an on‑premises Hadoop data lake: high hardware and electricity costs, resource competition, and painful concurrency issues that limited business users' ability to work with large datasets. To modernize their analytics stack and preserve existing BI investments, Rakuten engaged AtScale to migrate and virtualize their data platform and optimize query performance.

AtScale migrated Rakuten’s data to Snowflake on AWS, provided a semantic/virtual layer for Tableau, and optimized query execution and concurrency with intelligent aggregates. The move delivered measurable gains: 14x faster queries, a 30% reduction in load on the on‑prem cluster, a 4x cost reduction in a 10 TB test, and seamless access to data for dashboards (while migrating roughly $9.5 billion in U.S. e‑commerce sales data). AtScale’s solution lowered costs, improved surge capacity, and preserved Rakuten’s existing analytics workflows.
