You have a Fabric workspace that contains a lakehouse named Lakehouse1. Lakehouse1 contains a Delta Parquet table named FactSales. You use a Describe command to review the history of FactSales and…

Applying V-Order with OPTIMIZE optimizes the *layout* of current data files for read performance, not specifically to reduce the overall size by purging old versions or reducing the file count by removing unreferenced files.

Deleting the table would remove all data and metadata, which is an extreme measure and not a solution for managing table size and file count while retaining the table's current data.

The OPTIMIZE command primarily consolidates many small data files into fewer, larger files to improve read performance. While it reduces the *number* of files, its main purpose is not to reduce the *overall size* by purging old versions based on retention policy, which VACUUM handles.

The VACUUM command in Delta Lake is used to remove data files that are no longer referenced by the current version of the table and are older than the specified retention threshold. This directly reduces the overall storage size of the table and can decrease the number of underlying files by purging historical, unreferenced data, aligning with the goal of managing many versions and a retention policy.
