From transactions to analytics: where do we go from here?

A presentation at DataEngBytes 2026 in in Auckland, New Zealand by Marta Paes

In this talk, we’ll walk through the evolution of CDC as the enabler for high-performance, real-time analytics on transactional data, and explore what’s missing to make it work for the 99%.

A decade after Debezium entered the scene and commoditized Change Data Capture (CDC), we’re still struggling to bridge OLTP and OLAP for analytics. Expensive batch jobs evolved into overcomplicated streaming architectures, HTAP promised to ditch the need for data movement, someone told us to “just use Postgres”. How much progress have we made, and where do we go from here? We’ll share lessons learned over the past decade seeing hundreds of customers run CDC at scale, and how we can use them to build best-of-breed experiences for high-performance, real-time analytics.

Key Takeaways:

  • Learn how CDC evolved over the past decade
  • Understand the trade-offs between different architectures for CDC
  • See what works at scale for teams without massive engineering resources
  • Explore what’s next for CDC and unified data stacks
