-------------------------------------
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.
