Istvan Toth commented on PHOENIX-7380:
--------------------------------------
Maybe the connector already pushes everything down that is possible.
Need to investigate more.
> Do not limit pushdown to conjunctions in Hive connector

> Key: PHOENIX-7380
> URL: https://issues.apache.org/jira/browse/PHOENIX-7380
> Project: Phoenix
> Issue Type: Improvement
> Components: connectors, hive-connector
> Reporter: Istvan Toth
> Priority: Major
>
> Working on the Hive connector code, I noticed that it only pushes down
> conjunctions.
> This may have been correct in the original (since removed) Hive indexing that
> the code is based on, but the restriction doesn't seem to be necessary in the
> Phoenix case.
> I see no reason not to push down disjunctions to Phoenix. In fact, AFAICT any
> expression that can be evaluated on single row (no aggregates) can be pushed
> down to Phoenix without any problems, and should benefit from the distributed
> Phoenix processing, indexes, etc.
