During performance tuning of a Power BI Desktop model in Import mode, you discover that a fact table is 1.4 GB; VertiPaq Analyzer shows a long-text "Comments" column-unused in visuals, relationships, measures, or RLS-consumes 35 % of the table's size. You need to reduce memory consumption without affecting existing reports. Which action will provide the greatest improvement?
Move the Comments column into a separate calculated table and delete it from the fact table.
Change the column's Default summarization setting to Do Not Summarize.
Hide the Comments column in Report view to prevent authors from selecting it.
Remove the Comments column in Power Query so it is not loaded into the model.
Removing a column before it is loaded (vertical filtering) eliminates its dictionary and data pages from VertiPaq, directly shrinking the model and speeding up refresh and query execution. Hiding a column, changing its default summarization, or moving it to a calculated table keeps the column in memory, so the model size and performance issues remain.
