Subject Re: Support for cycles in spark streaming topology ?????

You can have diamonds but not cycles in the dependency graph.

But what you are describing really sounds like simple iteration, since
presumably you mean that the state of each element in the 'cycle'
changes each time, and so isn't really the same element each time, and
eventually you decide to stop. That is quite possible.
