How Materialized Views Enhanced Our Backend Performance

Materialized views store the results of expensive SQL queries so databases don’t have to recompute them on every request.

This guide explains how materialized views work in PostgreSQL, when to use them, and the trade-offs around refresh strategies, indexing, and data freshness.
