------------------------------------
Summary: 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
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.
