問題文
A logistics team must decide between a continuous pipeline and a triggered pipeline for their silver layer. Freshness matters but so does cost. How should they frame the trade-off?
選択肢
- Continuous keeps compute running to minimize latency, while triggered runs only when started and therefore pays only for the time it runs; the freshness requirement decides which cost is acceptable.
- Continuous is always cheaper because it avoids the repeated start-up costs that a triggered pipeline pays on every run, and start-up dominates the total for short flows. The freshness requirement therefore does not need to enter the decision.
- The choice does not affect cost because both modes run on serverless compute, so the company pays only for the data that is actually processed in either case.
- Triggered is always more reliable because a single flow failure does not stop other flows.
