In Power BI, what does the Aggregations feature in a composite model allow?

Accepted Answer

The Aggregations feature in a composite model enables pre-aggregation of large DirectQuery tables. This improves query performance by caching Import-mode summaries. The correct answer, B, is right because it accurately describes this pre-aggregation process. Options A, C, and D are incorrect as they misrepresent the Aggregations feature's purpose.
