Presentation: Write-Ahead Intent Log: A Foundation for Efficient CDC at Scale
Vinay Chella and Akshat Goel discuss the challenges of running traditional CDC across heterogeneous databases during peak order traffic. They explain how Debezium hit limits under high load and share how they built Write-Ahead Intent Log (WAIL) - a custom architecture that utilizes a dumb producer proxy and a smart consumer pattern to cleanly separate the intent from the state payload.

The proliferation of real-time data needs and heterogeneous database environments is pushing the limits of traditional Change Data Capture (CDC) solutions, necessitating more resilient architectures.
Efficient and scalable data access, especially CDC, is foundational for modern data-intensive applications, AI/ML pipelines, and enterprise integration, directly impacting operational efficiency and analytical capabilities.
This presentation introduces a custom architecture (WAIL) that bypasses traditional CDC limitations, potentially changing how large enterprises manage data synchronization and stream processing at scale.
- · Large enterprises with complex data ecosystems
- · Data engineering teams
- · Real-time analytics platforms
- · Distributed database vendors
- · Legacy CDC solutions reaching scalability limits
- · Organizations slow to adopt modern data architectures
Improved performance and reliability of data synchronization across diverse systems, reducing operational costs.
Accelerated development and deployment of applications reliant on real-time data, particularly in AI and ML contexts.
Potential for new patterns in data streaming and event-driven architectures to emerge as this approach gains traction, further fragmenting standard solutions.
