問題文
A dashboard must be refreshed every weekday at 7 am so that it is ready before the team arrives. No one will open it before then. Which mechanism produces the refreshed data?
選択肢
- A scheduled refresh setting on the dashboard, which runs the tile queries at the configured time whether or not anyone is viewing.
- A task on a schedule that rebuilds the reporting table, so the tiles read already-computed rows when someone opens the dashboard.
- A stream on the source table, which pushes the changes into the dashboard at the configured time.
- A materialized view over the daily reporting query, which Snowflake refreshes on the schedule given in its definition.
