The author argues against architectural cargo culting by demonstrating how PostgreSQL alone can handle complex requirements like event sourcing, caching, and temporal data without additional specialized databases. The article details a practical implementation using schemas, constraints, and triggers to manage transfers, balances, and audits within a single RDBMS. It includes benchmarks showing that this simplified stack can effectively replace multi-component architectures.
Background
Modern microservices architectures often lead to over-engineering by adding multiple specialized databases (e.g., Elasticsearch for search, Redis for cache, TimeScaleDB for time-series) on top of a primary RDBMS. This article challenges that trend by advocating for leveraging advanced PostgreSQL features to reduce operational complexity.
