Navis updated HIVE-7796:
------------------------
Attachment: HIVE-7796.1.patch.txt
> Provide subquery pushdown facility for storage handlers
> -------------------------------------------------------
>
> Key: HIVE-7796
> URL: https://issues.apache.org/jira/browse/HIVE-7796
> Project: Hive
> Issue Type: Improvement
> Components: StorageHandler
> Reporter: Navis
> Assignee: Navis
> Priority: Minor
> Attachments: HIVE-7796.1.patch.txt
>
>
> If underlying storage can handle basic filtering or aggregation, hive can
> delegate execution of whole subquery to the storage and handle it as a simple
> scanning operation.
> Experimentally implemented on JDBC / Phoenix handler and seemed working good.
> Hopefully open the code for those too, but it's not allowed to me yet.
