Materialized views are attractive because they move cost away from the request path. They are risky because they also move truth away from the source of record.

Precomputation changes the product contract

A materialized view is not just a technical optimization. It is a statement that some answers are worth serving fast even when they are not computed from the latest possible state.

The read path becomes calmer while the write path gets busier

This trade can be worthwhile, especially for dashboarding, aggregate reads, or heavily joined views. The cost is that the system now owns a projection pipeline that can fall behind, fail partially, or need replay.

The key decision is where freshness, ownership, and replay sit once the read answer is no longer computed on demand.

Rebuilds are the hidden bill

If rebuilding the read model is painful, the pattern was not fully designed. Mature teams ask how to backfill, validate, and cut over before they celebrate the query speedup.
