Spark SQL rank window function needs to sort the data locally and it relies on the execution plan *_SortExec_* to sort the data in each physical data partition. When the filter of the window rank (e.g. rank <= 100) is specified in a user's query, the filter can actually be pushed down to the SortExec and then we let SortExec operates top-N sort. Right now SortExec does not support top-N sort and we need to extend the capability of SortExec to support top-N sort. Or if SortExec is not considered as the right execution choice, we can create a new execution plan called topNSortExec to do top-N sort in each local partition if a filter on the window rank is specified. was: In Spark SQL, there are two types of sort execution, *_SortExec_* and *_TakeOrderedAndProjectExec_* . *_SortExec_* is a general sorting execution and it does not support top-N sort. *_TakeOrderedAndProjectExec_* is the execution for top-N sort in Spark.
