-----------------------------------------

Hi, I have started working on this issue and would be really gratefull if someone could have
a quick look on what I did so far. Did I go the right direction? Also I am not sure how to
approach the parralelism/sortPartition/partitionByRange issue. Generally any advices welcome.

The changes are here: https://github.com/dawidwys/flink/tree/tableSort

> 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?
