William Yang created PHOENIX-3328: ------------------------------------- Summary: Skip scan optimization failed for multi pk columns Key: PHOENIX-3328 URL: https://issues.apache.org/jira/browse/PHOENIX-3328 Project: Phoenix Issue Type: Bug Reporter: William Yang Priority: Minor
{code:sql} create table t1 (pk integer primary key, a integer); create table t2 (pk1 integer not null, pk2 integer not null, a integer constraint pk primary key (pk1, pk2)); explain select * from t1 where (pk > 10 and pk < 20) or (pk > 30 and pk < 40); explain select * from t2 where (pk1 > 10 and pk1 < 20) or (pk1 > 30 and pk1 < 40); {code} The first SELECT statement will use skip scan filter for two ranges, so as the second one. But actually the WhereOptimizer failed doing so and using a full table scan instead. This happens for tables have multi PK columns. -- This message was sent by Atlassian JIRA (v6.3.4#6332)
