The CTO Podcast with Fexingo · 2026-07-20 · 9 min
In this episode, Lucas and Luna dive into how Notion's engineering team rebuilt its real-time sync engine to handle over 100 million blocks of content without breaking. They explore the specific architectural decisions - switching from a monolithic sync to a delta-based CRDT system - and the performance gains that followed, including a 40% reduction in sync latency. Lucas compares it to how Google Docs handles collaborative editing, and Luna questions whether the trade-offs were worth it for a product that prioritizes simplicity. The episode also touches on the cultural shift within Notion's engineering org when co-founder Simon Last stepped in as interim CTO.
