Choose raw-only vs incremental materialized views vs refreshable materialized views

Principle

Real-time workloads should not be forced into either “everything raw” or “precompute everything.” The correct choice depends on freshness, query repetition, and transformation complexity.

Decision framework

Condition	Recommendation	Category
Queries are ad hoc and freshness matters most	Query raw tables	derived
Repeated aggregation pattern over append-only data	Incremental MV	official
Complex joins or scheduled batch recomputation	Refreshable MV	official
Very hot dashboard or alerting path	Incremental rollup table plus raw table fallback	derived

Guidance

Recommendation: incremental MVs for repeated real-time aggregation

Why Incremental MVs are the documented best fit for continuously maintained rollups over insert streams.

Recommendation: refreshable MVs for heavier joins or scheduled transforms

Why Refreshable MVs better fit complex transformations that do not need per-row trigger semantics.

Recommendation: dual-path design for hot dashboards

Why A raw table preserves flexibility while a rollup path protects latency-sensitive workloads.

Validation

Identify repeated dashboard queries
Compare raw scan cost against incremental aggregation maintenance
Confirm whether the source is append-only enough for incremental MV semantics
