Client Overview

Booking.com, a leader in the online travel industry, sought to enhance its data infrastructure to improve the management of its extensive data systems. The company partnered with Blue Orange Digital to develop a robust data pipeline, aiming to boost its data processing capabilities significantly.

Project Execution

Blue Orange Digital collaborated closely with Booking.com’s data team to design and implement a sophisticated data infrastructure that supports both operational and analytics needs. A key component of this project was the development of a MySQL to Big Data Exchange (BDX) pipeline. This pipeline was integral to modernizing Booking.com’s analytics capabilities and integrating them with existing data governance standards.


The main challenges addressed by Blue Orange Digital included:

  • Replicating data from a transactional database (MySQL) to an analytical database (BDX), which is a combination of Snowflake’s architecture and Booking.com’s proprietary greenfield solutions including data governance technologies and transformation services using dbt.
  • Ensuring the architecture was cloud-native, utilizing Kubernetes for containerization, and effectively managing the platform with Apache Airflow.

Technologies Utilized

  • MySQL: Employed for robust database management.
  • Snowflake: Utilized for effective data integration, combining core Snowflake features with proprietary workflow.
  • Kafka: Used for real-time data streaming, enhancing data handling capabilities.
  • Cloud Services and Tools: AWS Lambda, SQS, EventBridge, and DynamoDB were integrated to support cloud-native operations.
  • Containerization: Kubernetes and Docker were implemented to ensure scalability and efficient deployment.
  • Platform Management: Apache Airflow was used for scheduling and orchestrating the data pipeline workflows.


The implementation of this advanced data pipeline significantly improved how Booking.com handles and processes data, setting the stage for more efficient and scalable IT operations. This initiative not only strengthened Booking.com’s data infrastructure but also showcased BOD’s ability to manage complex IT projects and fostered a foundation for continued collaboration.

Project Approach

  1. Proof of Concept to Implementation: The project transitioned from a POC to full implementation, validating the approach before scaling.
  2. Agile Methodologies: Agile ceremonies and collaboration were integral to the project’s success, ensuring adaptive planning and evolutionary development.
  3. Consultative Engagement: BOD provided thought leadership and a consultative manner, helping to prioritize deliverables and integrate seamlessly with Booking.com’s specific technologies and requirements.

Technical Evolution

The project marked a transition from a full Java stack to a more diversified development environment incorporating both Java and Python. This evolution was critical for setting standard pipeline flows that could be replicated and scaled across Booking.com as the company continues its broader tech stack modernization and migration from Hadoop to an internal Snowflake-based solution.


This case study exemplifies Blue Orange Digital’s commitment to leveraging deep technical expertise and strategic project management to overcome significant challenges and deliver substantial infrastructure enhancements. The successful execution of this project with Booking.com has not only optimized their data handling processes but also positioned them for future technological advancements and efficiencies.
