Thanks, I have two last requests, sorry for that.
Could you rename flink-generic to flink-language-binding-generic? The
problem is, that the package name is now flink-generic, it pops up like this in
maven central and so on without the information that it is actually a sub
package of flink-language-binding. This could be quite confusing.
In MapFunctin.py and FilterFunction.py you use map() and filter()
respectively. These operations are not lazy, i.e. in map() it does first apply
the user map-function to every element in the partition and then it collects
the results. This can become a problem if the input is very big. Instead we
should iterate over the iterator and output each element after mapping. This
keeps memory consumption low. Same applies to filter().
