hello all, I've read KeyedMessage in doc, in which KeyedMessage is described as tuple of topic, key, and value and its said that
> If a partition key is provided it will override the key for the purpose of > partitioning but will not be stored. Does it means that it is safe to just randomize value of key? is there any rules/ restrictions about key's value? Thank you, Regards, -- Muqtafi Akhmad
