Presentation: Write-Ahead Intent Log: A Foundation for Efficient CDC at Scale

📰 InfoQ AI/ML

Learn how to build a scalable CDC solution using Write-Ahead Intent Log (WAIL) to overcome the limitations of traditional CDC approaches and handle high traffic volumes

advanced Published 18 Jun 2026
Action Steps
  1. Design a custom architecture using a dumb producer proxy and a smart consumer pattern
  2. Implement a Write-Ahead Intent Log (WAIL) to separate intent from execution
  3. Configure the WAIL to handle high load and peak traffic
  4. Test the WAIL with heterogeneous databases
  5. Apply the WAIL to your existing CDC pipeline
Who Needs to Know This

Data engineers and architects on a team can benefit from this approach to improve the efficiency and scalability of their CDC pipelines, especially in high-traffic environments
