Stephan Ewen commented on FLINK-2230:
-------------------------------------
There have been many discussions about whether we want null support in the
tuples.
I am still big time sceptical. It makes the whole key handling and normalized
keys more complicated. And it costs performance.
Also, there are very easy workarounds (option type in scala, POJO types in Java)
