Document: How Guiding Principles Help Us Scale Engineering Operations

The whitepaper details Loom's approach to scaling engineering operations during periods of rapid growth. Faced with database bottlenecks and replication lag, Loom used guiding principles like "Do less, well" and "Buy first, build later" to address these challenges. They introduced read replicas, migrated to Amazon Aurora for improved performance, and employed flat model caching strategies. The paper highlights their strategic decisions, including the use of pgreplay for performance testing, and their successful transition to a more scalable infrastructure.
