 <Tip>
-  If you pre-aggregate at **day** granularity, the cache hits for `day`, `week`, `month`, `quarter`, and `year` queries. If you pre-aggregate at **month** granularity, the cache hits for `month`, `quarter`, and `year` — but **not** for `day` or `week`, since those require finer-grained data.

 When multiple pre-aggregates match a query, Lightdash picks the smallest one (fewest dimensions, then fewest metrics as tiebreaker).
