Hybrid Loading Strategies

Concepts: paFullVsIncremental

What They Want to Hear 'I run a cost crossover analysis. Incremental is cheaper when the delta is small relative to the full table. But when the delta exceeds roughly 30-40% of the table, full refresh is actually cheaper because it avoids the matching overhead. My default: incremental daily with a scheduled full refresh weekly. For tables with high churn, I adjust the crossover threshold based on observed merge duration vs full reload duration.' This is the answer that shows you think about incremental loading as an optimization, not a religion.
