問題文
A team is deciding where to register a dataset that another department already keeps in its own cloud storage bucket, under a directory layout that other tools also read. The team wants to query it from Databricks SQL without changing that layout or moving the files. Which registration fits?
選択肢
- Register it as an external table pointing at that storage location, so the files stay where they are and other tools keep reading them.
- Register it as a managed table, because managed tables can be pointed at any existing storage location while still letting the platform handle layout.
- Create a materialized view over the files so that the original layout is preserved and the view stays in sync with every write.
- Ask the other department to publish the directory as a share, because external tables cannot be created over storage owned by another team.
