> It would be great to support JOIN statement in Storm SQL.
> http://storm.apache.org/releases/1.0.1/Trident-API-Overview.html
> According to this page, Trident supports 'join' across multiple spouts which is done by synchronizing spouts. 
> This might be good start for Storm SQL join feature. This restricts the boundary of join to batch, but we're OK for now since aggregation is implemented via same restriction.
