DEFINITION

A Postgres feature that filters rows based on the query context. For multi-tenant SaaS: every SELECT automatically gets a tenant filter appended.

RELATED TERMS06
  • SSR (Server-Side Rendering)→

    HTML rendered by the server per-request, fresh for every user. Ideal for dynamic content (dashboards), but slower than SSG.

  • SSG (Static Site Generation)→

    Pages are produced at build time as HTML and served from a CDN. Near-zero TTFB. DField's own site runs this way across 111+ pages.

  • ISR (Incremental Static Regeneration)→

    SSG + timed regeneration: the HTML is static but regenerates on a schedule. Ideal for blog content · freshness with CDN speed.

  • Edge rendering→

    Code runs at the CDN edge closest to the user (Cloudflare Workers, Vercel Edge). Dynamic responses with ~10–50 ms TTFB.

  • RSC (React Server Components)→

    React components that run exclusively on the server and never ship to the browser. Result: less client-side JS and faster hydration.

  • LCP (Largest Contentful Paint)→

    Time until the largest visible element paints. Google Core Web Vitals passes under 2.5s · we usually land marketing pages under 1s.
