Cold Storage: The Simple Fix to Database Slowdowns

As databases grow with accumulated historical data, performance inevitably degrades—but resorting to expensive sharding or horizontal scaling often misses the real problem. Most production data is dormant: keeping old orders, logs, or events in active tables unnecessarily bloats indexes and increases IO pressure. The solution is surprisingly simple—separating 'hot' recent data from 'cold' archived data using partitioning, data warehouses, or object storage dramatically improves performance without major re-architecture.
