-----------------------------------
Summary: [Storm SQL] Drop Aggregate & Join support on Trident mode
Key: STORM-2200
URL: https://issues.apache.org/jira/browse/STORM-2200
Project: Apache Storm
Issue Type: Task
Components: storm-sql
Affects Versions: 2.0.0, 1.1.0
Reporter: Jungtaek Lim
Assignee: Jungtaek Lim
Priority: Critical
This was already discussed on dev@ mailing list. [1]
As aggregation and join don't make sense for streaming without windowing, we're
not ready to handle them on SQL semantic. Unless we're ready, it would be
better to drop them to not making any confusions. (Aggregation and join on
Trident semantic could be different from what users expect.)
