If the statistics are outdated, the optimizer might make suboptimal choices. - **Statistics mismatch**: even if statistics are current, they might not accurately reflect the data distribution, leading to incorrect cost estimations. - **Incorrect cost calculation**: the optimizer might miscalculate the cost of using an index due to complex query structures or data distribution. -- **Engine selection**: in some cases, the optimizer might select a storage engine that is not optimal for the query. +- **Inappropriate engine selection**: in some cases, the optimizer might select a storage engine that is not optimal for the query. - **Function pushdown limitations**: certain functions or operations might not be pushed down to storage engines, potentially affecting query performance. ## Statistics health
