 [^1]: The cost of generating index recommendations is highly variable. Index recommendations are generated by:
-1. Analyzing the query to find "hypothetical indexes" that may improve the performance of the query.
-2. Running the query optimizer as if the hypothetical indexes actually exist.
-3. Any hypothetical index in the final query plan becomes an index recommendation.
-
-Step 1 is not picky. Its goal is to cover all possible indexes that might help. 
-In general, the number of hypothetical indexes grows with the number of filtered columns 
-in the query.
-Step 2 can be fast for simple queries (<1ms), but the cost of optimization grows with 
-the number of joins, filters, and columns (>1s). 
-If Step 1 adds many hypothetical indexes, Step 2 will take longer because there are more query plans to explore.
