Revolutionizing Retail Data: 60% Faster Data Processing Through Teradata to BigQuery Migration
Challenge
Giant Tiger, a retail giant, faced challenges with their existing Teradata data warehouse and sought a more flexible and scalable cloud environment. Their data ecosystem was intricate, involving several databases, ETL processes, and downstream systems. Adastra helped Giant Tiger migrate from Teradata to Google BigQuery, thus overcoming several existing limitations.

Solution
The cloud migration was seamless thanks to a custom migration agent and BigQuery Data Transfer Service. Once it went live on GCP, Adastra noticed a drastic reduction in ETL batch processing times from up to 3 hours to mere minutes, significantly improving query performance and system efficiency. Furthermore, the implementation of data governance policies and user access controls streamlined data management, eliminating unnecessary data, and reducing costs.

Results
The migration from Teradata to BigQuery brought many benefits to Giant Tiger. They experienced a paradigm shift in how they approached data, transitioning from a largely operational standpoint to a more strategic, data-driven focus.
The success of the project didn’t just solve their existing issues but also set our client up with a scalable, future-proof data infrastructure, enabling them to be more agile and data-driven in their decision-making process.
