Durable by Design: Inside n8n's New Execution Engine

n8n is building a new execution engine that records every step durably and drives progress through events rather than a call stack. Instead of holding state in memory for the life of an execution, each step is persisted as it happens — so a workflow can pause, resume, or recover without losing its place.

In this lightning talk, one of the engineers building it shares how the new execution flow works at a high level, what problems it's designed to solve, and what it changes for the reliability, flexibility, and scalability of your workflows. You'll also get an honest look at where the project stands today.
