### Describe the bug This was brought up before here https://github.com/apache/datafusion/issues/15265 From the top of my head my I think we could use these in: - Join swapping strategy - Optimal number of partitions in Hash Join partitioning where we use Hash Partitioning. - Filter pushdown decision: if we have an very low NDV it might not be worth pushing down // computing predicates? This would likely require further investigation into how other query engines use NDV for optimization decisions 🤔 ### To Reproduce _No response_ ### Expected behavior _No response_ ### Additional context _No response_ -- This is an automated message from the Apache Git Service.
