¿Cuál de estos NO es un método para optimizar tu AMC de SQL?

Adding redundant subqueries is not a method to optimize SQL in Amazon Marketing Cloud (AMC); instead, it typically increases query complexity and execution time. Redundant subqueries can force the database to perform unnecessary operations or re-evaluate the same data multiple times, leading to slower performance and higher processing costs. Filtering records early in the query, optimizing the order of operations, and optimizing JOIN clauses are all effective strategies for SQL optimization in AMC. Filtering early reduces the dataset size that subsequent operations must process. Optimizing the order of operations ensures that less resource-intensive tasks are performed before more complex ones. Optimizing JOIN clauses, such as using appropriate join types and conditions, minimizes the number of rows processed during joins, which are often performance bottlenecks.
