Designing SQL Server Pipelines That Are Ready for AI Before You Actually Need AI
The article argues that AI readiness starts with robust SQL Server schema design, not with machine‑learning models. It highlights that stable, non‑recycled primary keys, preserved historical records, and clear audit columns are essential for future feature engineering. By separating raw events from derived attributes and avoiding overloaded or free‑text‑only columns, organizations keep data flexible for analytics. The piece provides a practical checklist to assess whether a database can support downstream AI pipelines without costly retrofits.
Radim Marek: PostgreSQL Statistics: Why Queries Run Slow
PostgreSQL’s query planner relies on catalog statistics from pg_class and pg_statistic to estimate costs. When these statistics become stale—due to bulk loads, schema changes, or insufficient vacuum—the planner can choose inefficient plans, turning milliseconds queries into minutes. The article explains...
