Stripe Uses Graph Search and State Machines to Automate Database Remediation
Scored daily by a customisable AI persona to surface the most relevant engineering leadership news.
Stripe's graph-based database remediation automation, highly technical and directly relevant to observability and platform engineering.
Stripe automated database incident recovery by modeling its MongoDB infrastructure as a graph, using Dijkstra's algorithm and state machines to compute and execute remediation plans dynamically. This approach replaced a brittle, plugin-based system, reducing database-related pager alerts by 30% (200 fewer pages per year) and eliminating 12 days of unhealthy shard states annually. The system adapts to different shard layouts and partial failures, and Stripe plans to extend it to topology changes and blue-green deployments.
