I based this on [Board 2 here](https://drive.google.com/a/gopivotal.com/folderview?id=0B2yhsfF9zZ71LTBtdVJfd19oSkk&usp=sharing) (`partition.count`).

But it is only needed by the producer so `producer.moduleCount` would work - I coded the consumer props (key expression etc) as `consumer.*` props so, right now, there are no `partition.*` props for the consumer.
