I've designed two processors with a different topology.
The issue is that in the firs topology in one node i was able to associate
diffrent messages (key,value) where the key could be the same and so i was able
to do something like countbyKey.
In the second example when i liked to do the same i noticed that this was not
possible. eny new value assiated to a key is erased by the next value so there
is a respect to the unicity of the key.
I think this is really weird.
Does anybody has an explenation or a suggestion ?
Thanks in advance,
