The baseline numbers will help you determine if you're getting the intended benefit from the feature. Memory grant feedback (MGF) is an existing feature that adjusts the size of the memory allocated for a query based on past performance. However, the initial phases of this project only stored the memory grant adjustment with the plan in the cache – if a plan is evicted from the cache, the feedback process must start again, resulting in poor performance the first few times a query is executed after eviction. The new solution is to persist the grant information with the other query information in the Query Store so that the benefits last across cache evictions. Memory grant feedback persistence and percentile address existing limitations of memory grant feedback in a non-intrusive way.
