Re: broadcast() without arguments
Hello,
The broadcast() without arguments can be used the same way as a
regular data stream, i.e. regular transformations can be applied to
it. The difference is that every element will be sent to all
downstream subtasks and not just one.
The difference with broadcast() with arguments is that the latter only
allows to connect the broadcasted stream with another one, for example
to match the elements from two streams against each other.
Regards,
Roman
