------------------------------------------
Summary: Phoenix Query With Multiple 'OR' operators does a full
range scan when it is a tentant specific connection
Key: PHOENIX-3644
URL: https://issues.apache.org/jira/browse/PHOENIX-3644
Project: Phoenix
Issue Type: Bug
Reporter: saikiran perumala
I was looking at explain plan for IN / OR operators in a where statements, I
got some conflicting results
Non tenant query :
here IN AND operator are on PK
Explain Select * from CUSTOM_ENTITY."CUSTOM_ENTITY_DATA_NO_ID" Where
Organization_id IN ('00Dxx0000001i28', '00Dxx0000001i29') AND Key_prefix =
'z0D';
Explain Select * from CUSTOM_ENTITY."CUSTOM_ENTITY_DATA_NO_ID" Where
(Organization_id = '00Dxx0000001i28' OR Organization_id = '00Dxx0000001i29')
AND Key_prefix = 'z0D';
Both give same result :
CLIENT PARALLEL 32-WAY POINT LOOKUP ON 2 KEYS OVER
CUSTOM_ENTITY.CUSTOM_ENTITY_DATA_NO_ID
Tenant Specific View:
here IN AND operator are on PK
explain SELECT * FROM CUSTOM_ENTITY."z0D" WHERE C00NXX000001DIBOEAS
IN('ROW-THREAD_1-VAL-99999','ROW-THREAD_1-VAL-99998','ROW-THREAD_1-VAL-99997')
this is the query plan
CLIENT PARALLEL 32-WAY POINT LOOKUP ON 3 KEYS OVER
CUSTOM_ENTITY.CUSTOM_ENTITY_DATA_NO_ID
SERVER FILTER BY PageFilter 100
SERVER 100 ROW LIMIT
CLIENT 100 ROW LIMIT
But when there is an OR say for this query
explain SELECT * FROM CUSTOM_ENTITY."z0D" WHERE
(C00NXX000001DIBUEAS='ROW-THREAD_1-VAL-99998' OR
C00NXX000001DIBUEAS='ROW-THREAD_1-VAL-99997')
This is the query plan :
CLIENT PARALLEL 32-WAY RANGE SCAN OVER CUSTOM_ENTITY.CUSTOM_ENTITY_DATA_NO_ID
['00Dxx0000001i28','z0D']
SERVER FILTER BY (C00NXX000001DIBUEAS = 'ROW-THREAD_1-VAL-99998' OR
C00NXX000001DIBUEAS = 'ROW-THREAD_1-VAL-99997')
SERVER 100 ROW LIMIT
CLIENT 100 ROW LIMIT
In a tenant specific view IN and OR operators on a PK return different query
plan, OR filter is doing a full range scan instead of a Point query.
