In the context of MariaDB's query planner, what is the primary role of the "cost model" in determining the optimal execution plan for a given query?
When analyzing a query plan that exhibits a high cost associated with a "ref" access method for a join, what is the most likely underlying issue that a specialist would investigate first?
asks about the *likely underlying issue*, not the means of investigation. Question: Consider a scenario where MariaDB consistently chooses a full table scan for a `SELECT` statement involving a `WHERE` clause on a column that has an index. What advanced tuning technique would a specialist consider *before* resorting to adding a composite index?
