Remove the files: Run the VACUUM command on a schedule.

Combine the files: Set the optimizeWrite table setting. or Run the OPTIMIZE command on a schedule.

To remove files that are no longer used, the VACUUM command is used in Delta Lake to clean up invalid files from a table. To combine smaller files into larger ones, you can either set the optimizeWrite setting to combine files during write operations or use the OPTIMIZE command, which is a Delta Lake operation used to compact small files into larger ones.

For the Customers table, where the requirement is to create a new version of the row, you would use:

Type 2 SCD: This type allows for the creation of a new record each time a change occurs, preserving the history of changes over time.

For the Products table, where the requirement is to overwrite the existing value in the latest row, you would use:

Type 1 SCD: This type updates the record directly, without preserving historical data.

Comprehensive Detailed Explanation

Step 1: Reviewing the provided DAX expression

SWITCH(

SELECTEDVALUE(Metric[Metric]),

"# of Customers", "#",

"Gross Margin %", "0.00%",

"#,###"

)

This is applied as a dynamic format string.

It changes the display formatting of the Value measure depending on the selected metric.

Step 2: Identify the feature

The screenshot shows Format = Dynamic in the Power BI Modeling tab.

This confirms that a dynamic format string has been applied.

So, for the first blank → dynamic format string.

Step 3: Identify the output formats

If the metric = # of Customers → format is "#" → whole numbers.

If the metric = Gross Margin % → format is "0.00%" → percentages.

Fallback → "#,###" → also whole numbers.

Thus, the measure supports both whole numbers and percentages.

So, for the second blank → percentages or whole numbers.
