You are creating a Delta Lake table in Databricks to store IoT sensor readings for a manufacturing plant. The dataset contains the following columns:

event_date (date of reading)
machine_id (about 50 machines)
temperature (numeric)
vibration_level (numeric)

The table will store 10 years of data, and queries almost always filter by event_date (e.g., WHERE event_date BETWEEN '2024-01-01' AND '2024-01-31'). Occasionally, queries also filter by machine_id.

Which table definition BEST optimizes query performance and storage layout?
