Query Store is off when you need it most

Without a flight recorder for plans, every regression becomes folklore. Why enabling Query Store is a standard health-check recommendation.

When performance regresses after a release, stats update, or night-time maintenance, teams without Query Store argue from memory. Teams with it compare plans.

Health-check recommendation

For supported versions and editions, enabling Query Store on critical databases is one of the highest ROI operational changes available.

Configure it deliberately

  • Size storage for the workload
  • Avoid silent read-only mode when full
  • Capture settings that match how volatile the app is
  • Train the team to use it during incidents

What it unlocks later

  • Plan regression detection
  • Forcing known-good plans when needed
  • Evidence for application teams
  • Cleaner performance engagements (less time hunting, more time fixing)

Free check positioning

We often recommend Query Store during the free health check so the next incident — and any paid tuning work — starts with evidence instead of guesswork.
