> [Storm SQL] Support automatic spout parallelism based on DataSource metadata
> ----------------------------------------------------------------------------

>
> 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.
