Summary: Support JOIN statement in Storm SQL
Key: STORM-2057
URL: https://issues.apache.org/jira/browse/STORM-2057
Project: Apache Storm
Issue Type: New Feature
Components: storm-sql
Reporter: Jungtaek Lim
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.
