materialized view
Persist a query result and define how it becomes current again.
Use this when A dashboard repeats an expensive aggregate that can tolerate some lag.
without the term
“This dashboard recomputes the same large aggregate every time. Store a result and define when it updates.”
with the term · How do you ask a model for materialized view?
Evaluate a materialized view for this aggregate. Define refresh and freshness, then check results before and after a source change.
What is materialized view?
A materialized view stores the result of a query. In PostgreSQL, reading it uses stored rows and refreshing recomputes the result; other engines may support incremental maintenance.
Why does materialized view matter when vibe coding?
An agent can replace a query with a stored result without scheduling refreshes or showing its age.
How do you do materialized view?
Choose a freshness budget, refresh method, and failure handling. Change source data, verify the view’s documented lag, then verify the refreshed aggregate.
What goes wrong with materialized view?
A normal view does not persist results. A materialized view can become stale and its refresh can be expensive.
