> We've seen before that we crash when we have a vertex which receives a lot of messages and we don't use a combiner. That is because the total size of serialized messages for that vertex is bigger than the allowed size of an array. 
> We should implement OutputStream which can handle arbitrary size of data and add an option to use that kind of stream for messages.
