Animations for System Builders
The author discusses using LLMs to create animations that visualize complex system failures, such as database metastability and Raft cluster issues. These visual aids help engineers understand how software systems behave under stress and load.
Why it matters
Visualizing abstract system failures is critical for improving software reliability and debugging production-level infrastructure.
One of the things I love using LLMs for is helping me understand systems better. In the Strands Decider post I wrote about how I often ask ask me questions to check I understand this . The other technique I’m enjoying right now, and am delighted to see folks around me using too, is building animations.
Animations can help us build an intuition for how and why systems work, or how and why they fail.
Here’s one example: did you know that a Raft cluster can lose writes if even one of the cluster members has a storage layer that lies about fsync() ?
