---------------------------------------------------------------------

The hashCode() assumption isn't documented. It is also not sufficient, there should be control in the operator itself how the hash code is computed. I think we should revisit the options for tracking the state.
 
Is there an example someone can start from for this operator? Documentation?

> The abstract kafka output operator needs to be refactored
> 1. Needs to set some mandatory properties on operator level instead of kafka property level.
> 2. More document and examples
> 3. Find a standard way to achieve exactly once in both 0.8 and 0.9
> More will be added when working on the ticket
