ETL Processes for a Retail Energy Company

Industry: Energy

THE CHALLENGE

Enhancing Performance and Reducing Costs

The Operations and Engineering teams at a retail energy company faced challenges with their critical ETL (Extract, Transform, Load) processes. These processes required significant performance improvements and cost reductions in infrastructure.

The client needed a solution that supported seamless horizontal scalability and introduced a modern backend architecture to meet growing demands.

The Hidden Pain Points

The existing infrastructure presented the following challenges:

Performance Bottlenecks: Long processing times (up to 6 hours) hampered efficiency and delayed critical business operations.
High Costs: Legacy systems incurred significant computation and storage expenses, including reliance on costly third-party services.
Scalability Constraints: The infrastructure struggled to handle increasing workloads and lacked the flexibility for horizontal scaling.
