      Description

      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.
