   Hi @xiaoyong-z,  I can receive some of the tasks from the document. Specifically I would like to start out with the case. 
   - 1.Implement StreamAggregate that handles pre-sorted data (where the data is already sorted according to the grouping keys/ partition keys). (Corresponds to 2nd step in the document I guess.)
   
   If you are not working already on this feature.
