Kerbal Space Program: A Journey into Mod Metadata Herding
summary
Builds and operations of the Comprehensive Kerbal Addon Network evolve from a brittle, monolithic cron-and-mono pipeline into a set of decoupled services running in AWS, using AWS SQS/DynamoDB, containers, and an inflator that caches hashes to avoid recomputing downloads. The service tracks ~1,500 mods for ~100,000 users, adds automatic stale marking and version-handling, drops CPU and cost (to about $30/month), and achieves indexing runs of 15 minutes for 1500 mods—roughly a tenfold efficiency gain.
