問題文
A logistics team must decide whether to enable Photon on a cluster that runs a mix of short lookup queries and long batch transformations. Which two considerations apply? (Select two.)
選択肢
- Photon instance types consume DBUs at a different rate than the same instance type running the non-Photon runtime, so the cost per hour changes.
- Photon requires the transformations to be rewritten in SQL, because the DataFrame API is not supported.
- Photon must be enabled through a cluster policy, because it cannot be set on individual clusters.
- Photon accelerates all queries proportionally, so the short lookups improve by the same percentage.
- Photon provides the greatest benefit for longer-running queries that process large datasets, so the batch transformations should improve.
