[GitHub] [flink] mans2singh opened a new pull request #8839: [FLINK-12952][docs] Minor doc correction to incremental window functions

mans2singh opened a new pull request #8839: [FLINK-12952][docs] Minor doc correction to incremental window functions
URL: https://github.com/apache/flink/pull/8839
 
 
   
   ## What is the purpose of the change
   
   Minor correction to documentation regarding incremental windows functions
   
   ## Brief change log
   
   The Flink documentation [Window Functions](https://ci.apache.org/projects/flink/flink-docs-release-1.8/dev/stream/operators/windows.html#window-functions) mentions that
   
   > The window function can be one of ReduceFunction, AggregateFunction, FoldFunction or ProcessWindowFunction. The first two can be executed more efficiently
   
   
   It should perhaps state (since FoldFunction, though deprecated, is also incremental):
   
   > The first three can be executed more efficiently
