Main difference: use case and scale. Partition insight calculations by region or brand to parallelize compute and reduce blast radius. Materialize intermediate aggregates in staging insights before final RFM composite. Pick based on your integration pattern and team capability. Calculated insights at scale need job architecture and freshness contracts—not bigger schedules alone. Document the decision in an ADR and align with enterprise standards.
Architect Perspective
Calculated insights at scale need job architecture and freshness contracts—not bigger schedules alone. Treat insights as published datasets with version and SLA.
