Samarth Jain created PHOENIX-1298:
-------------------------------------
Summary: Queries on fixed width type columns that have an index
declared on them don't use that index with Row Value Constructors.
Key: PHOENIX-1298
URL: https://issues.apache.org/jira/browse/PHOENIX-1298
Project: Phoenix
Issue Type: Bug
Affects Versions: 5.0.0, 4.2, 3.2
Reporter: Samarth Jain
Happens when the index is on a column whose data type is fixed width. If V1 is
made of type VARCHAR, then the test passes.
{code}
@Test
public void testRVCUsingPkColsReturnedByPlanShouldUseIndex() throws
Exception {
Connection conn = DriverManager.getConnection(getUrl());
conn.createStatement().execute("CREATE TABLE T (k VARCHAR NOT NULL
PRIMARY KEY, v1 CHAR(15), v2 VARCHAR)");
conn.createStatement().execute("CREATE INDEX IDX ON T(v1, v2)");
PhoenixStatement stmt =
conn.createStatement().unwrap(PhoenixStatement.class);
String query = "select * from t where (v1, v2, k) > ('1', '2', '3')";
QueryPlan plan = stmt.optimizeQuery(query);
assertEquals("IDX",
plan.getTableRef().getTable().getTableName().getString());
}
{code}
Instead of going through the index table, the query ends up using the data
table.
