Migrating Enterprise Databases to SQLite/PostgreSQL
A comprehensive study on why modern teams are shifting away from commercial database licensing, and how to structure local SQLite layers for high concurrency.
Commercial database licensing can consume up to 30% of an early-stage IT budget. By utilizing optimized PostgreSQL architectures and running SQLite caching nodes for read-heavy operations, companies can own their stack while retaining sub-millisecond response times. This guide goes through indexing rules, connection pool throttling, and secure container configs. We discovered that by separating read and write nodes and implementing a robust caching layer with Redis, the overall latency drops significantly. Furthermore, the migration process itself can be heavily automated using custom scripting pipelines.
