Description

In order to implement a FLINK-2099 prototype that uses the Table APIs code generation facilities, the Table API needs a sorting feature.

I would implement it the next days. Ideas how to implement such a sorting feature are very welcome. Is there any more efficient way instead of .sortPartition(...).setParallism(1)? Is it better to sort locally on the nodes first and finally sort on one node afterwards?
