> It would be better to receive metadata from Data Source, especially producer 
> which can give some hints to optimize. 
> A notable kind of hint is parallelism hint. In storm-kafka we know that 
> normally it's best to set parallelism to same as topic's partition count so 
> that Spouts can pull the data from all partitions in parallel.
> We can apply non-query optimizations start from here.
