Scalable Casino Warehouse Cutting ETL Costs by 90%

About Client

The client is an award-winning online gaming group based in Malta, operating multiple brands within a regulated casino enterprise environment. The organization manages high transaction volumes across gaming platforms, player engagement systems, and compliance workflows, making data reliability critical to daily operations.

Background

A fundamental part of the client’s data-first approach was ensuring data acted as a single source of truth for the entire casino enterprise. This ensured transparency, readability, higher reliability, and more valuable insights across business, risk, and marketing teams.

However, building a centralized casino warehouse introduced challenges across architecture design, data governance, and master data management. While some issues were technical, many stemmed from business-level decisions that limited scalability and slowed insight generation.

Challenge

The client’s existing data architecture posed serious performance and cost risks:

  • The platform was not scalable enough to support the growing needs of a multi-brand casino enterprise
  • Data was managed inconsistently, making processing slow and operationally expensive
  • High overall costs were incurred to maintain a complex and fragmented system

These limitations prevented the organization from supporting modern analytics and emerging confluent gambling use cases, such as cross-brand player analytics and consolidated reporting.

The Objective

Build a scalable Enterprise Data Warehouse that would:

  • Speed up processing time and ensure no query failures
  • Implement a standard data framework across the casino enterprise
  • Consolidate multi-brand data into a centralized casino warehouse for easier extraction and analysis
  • Support future growth and advanced confluent gambling use cases without re-architecting the platform

Our Solution

Stakeholder workshops were conducted to define a single, enterprise-wide set of KPIs and variables, resolving long-standing data consistency issues across the casino enterprise.

  • A logical data model and governance framework were designed, covering standardized KPI definitions, user access control, and data security
  • The Enterprise Data Warehouse was built on Amazon Redshift, using the existing Hive-based data lake on Amazon S3 as the source
  • AWS Glue handled ETL jobs, orchestrated via Apache Airflow
  • Redshift Spectrum enabled direct querying of S3 data, bypassing Hive to improve query performance
  • Python Shell Glue jobs invoked Redshift stored procedures to load and process data efficiently

This architecture modernized the casino warehouse to support scalable analytics and emerging confluent gambling use cases, while significantly reducing processing overhead and operational cost.

Outcome

A scalable Enterprise Data Warehouse was successfully implemented for the casino enterprise

  • A standardized data framework consolidated multi-brand data, ensuring enterprise-wide consistency and high-speed processing
  • Future casino brand acquisitions now require minimal integration effort into the centralized casino warehouse

 

ETL costs were reduced by 90.44% through Redshift Spectrum and Python Shell Glue jobs

The Enterprise Data Warehouse was delivered in 4 months, meeting urgent business timelines

1.3 TB (compressed) of historical data from the largest table was loaded into the warehouse within 48 hours, enabling faster adoption of analytics and confluent gambling use cases
