---------------------------------------
Summary: Improve the optimizer to consider all plans and prefer
regular over reverse scans
Key: PHOENIX-6460
URL: https://issues.apache.org/jira/browse/PHOENIX-6460
Project: Phoenix
Issue Type: Improvement
Reporter: Swaroopa Kadam
Fix For: 5.1.1, 4.17.0
In QueryOptimizerTest, following test fails, as it uses IDX over view
@Test
public void testChooseIndexOverTable_diffOrder() throws Exception {
Connection conn = DriverManager.getConnection(getUrl());
conn.createStatement().execute("CREATE TABLE t (k INTEGER NOT NULL, v1 VARCHAR
NOT NULL, v2 VARCHAR CONSTRAINT"
+ " PK PRIMARY KEY (k, v1)) IMMUTABLE_ROWS=true");
conn.createStatement().execute("CREATE VIEW v(v4 VARCHAR) AS SELECT * FROM t");
conn.createStatement().execute("CREATE INDEX idx ON v(v1 DESC) INCLUDE (v4)");
PhoenixStatement stmt = conn.createStatement().unwrap(PhoenixStatement.class);
QueryPlan plan = stmt.optimizeQuery("SELECT v1 FROM v ORDER BY v1");
assertEquals("V", plan.getTableRef().getTable().getTableName().getString());
}
