Is Your UI Designed to Handle Large Data Volumes Gracefully?

Category: UI
Audience: Frontend engineers, product designers, and backend engineers defining pagination or filters

🔍 What This Perspective Covers

A good UI shows just enough.

Not too little.
Not too much.
And never too slow.

⚠️ UI Load Pitfalls

  • Fetch-all endpoints crash browsers with large result sets
  • Slow tables that rerender entire DOM trees for 1000+ rows
  • Users can’t filter or search → manually scroll and scan
  • Data arrives async, but layout is designed for sync

âś… Healthier Load Strategies

  • Define and enforce page size limits in API + UI
  • Provide filters, search, and progressive disclosure by default
  • Render skeletons or optimistic placeholders to mask delay
  • Prefetch adjacent pages, but load incrementally
  • Consider adaptive pagination for high-data users

🧠 Principle

Performance isn’t just speed.
It’s perceived responsiveness.

âť“ FAQ

  • Q: Can’t we just paginate everything?
    A: Not if users need to search before loading a page.

  • Q: Should frontend show a spinner?
    A: Only if it explains the delay.
