Notion details its CRDT-based collaborative editor handling millions of ops per minute
dejavucoder · x · 2026-09-19
Notion's engineering blog explains how it rebuilt text editing for real-time collaboration: until 2025, block records used last-write-wins, so concurrent edits within a block were lost, and Offline Mode would worsen data loss. The team adapted CRDT research into a conflict-free rich-text system fitted to Notion's block-based document model, now processing millions of operations per minute — one of the largest CRDT deployments in production.
