[GitHub] spark issue #21859: [SPARK-24900][SQL]Speed up sort when the dataset is smal...

    for small queries, can we just do
    ```
    val df = table.filter(...).cache()
    df.sort(....)
    ```
    
    We should carefully make trade off between the SQL engine complexity and 
user-benefits. How userful is this feature?
