Pedro Gandola created PHOENIX-2597:
--------------------------------------
Summary: Local Indexes are not used to query views
Key: PHOENIX-2597
URL: https://issues.apache.org/jira/browse/PHOENIX-2597
Project: Phoenix
Issue Type: Bug
Affects Versions: 4.4.0, 4.7.0
Reporter: Pedro Gandola
I've noticed that Phoenix (using version 4.4) when querying a view it does not
consider the original table local indexes to optimise the query.
If I explain my query over the original table it's using the local index
properly:
{code:sql}
EXPLAIN SELECT * FROM BIDDING_EVENTS WHERE wTs IS NOT NULL;
CLIENT 300-CHUNK PARALLEL 300-WAY RANGE SCAN OVER _LOCAL_IDX_BIDDING_EVENTS
[-32768]
SERVER FILTER BY "WTS" IS NOT NULL
{code}
However, If I create a view using the exact same query and explain I get a full
scan.
{code:sql}
CREATE VIEW WINS_VIEW AS SELECT * FROM BIDDING_EVENTS WHERE wTs IS NOT NULL;
EXPLAIN SELECT * FROM WINS_VIEW;
CLIENT 300-CHUNK PARALLEL 1-WAY FULL SCAN OVER BIDDING_EVENTS
SERVER FILTER BY WTS IS NOT NULL
{code}
Version 4.7 is affected as well.
