Designing a Data Migration Pipeline: Schema Mapping, Incremental Sync, and Zero-Downtime Cutover

Moving data between systems at scale is not a copy operation. It is a multi-phase pipeline with schema transformation, CDC-based incremental sync, dual-write coordination, and a cutover sequence you can abort at any point. This article covers the full architecture.

Designing a Database Proxy: Connection Pooling, Query Routing, and Read/Write Splitting at Scale

Database proxies like PgBouncer, ProxySQL, and Vitess solve connection exhaustion, read scaling, and failover at the infrastructure layer so your application does not have to. Here is how they work under the hood and when each strategy makes sense.
