Use the lookup operator. The lookup operator optimizes the performance of queries where a fact table is enriched with data from a dimension table. It extends the fact table with values that are looked up in a dimension table. For best performance, the system by default assumes that the left table is the larger fact table, and the right table is the smaller dimension table.
