Declarative Data Service Routing for Polyglot Persistence
· 4 min read
In modern complex application architectures, polyglot persistence has almost become a standard configuration. Within a single system, core transactional data may require PostgreSQL for strong consistency guarantees, massive execution logs might need Meilisearch for full-text search, state information could be thrown into Redis for ultra-high-speed caching, and local development might even downgrade to rusqlite.
The trade-off is coordination complexity: connection pools, provider SDKs, and routing decisions can leak into application code.
