To convert CSV files in Subfolder1 into Delta with V-Order optimization, which Lakehouse Explorer feature should you use?

• A. Load to Tables feature
• B. Copy to Delta option
• C. Export Data feature
• D. Convert to Delta via CLI

Answer: (A)

Loading CSVs into a Delta table with optimization is what the Load to Tables feature is designed to do. It can take the CSV files found in Subfolder1, convert them into a Delta table, and apply V-Order (Z-order) optimization during the load so related data is co-located on disk. This makes queries that filter on the most commonly used columns faster, because the data layout is arranged to minimize reads. The other options don’t provide this combined ingestion-and-optimization flow. Copying to Delta usually focuses on moving or duplicating existing Delta data, not creating a new Delta table from a set of CSV files with V-Order. Export Data is about moving data out of the lakehouse, not converting a folder of CSVs into a Delta table with optimization. Convert to Delta via CLI is a separate conversion step that generally doesn’t integrate the V-Order optimization during the ingestion from a directory like Subfolder1.
