Shuo Cheng created CALCITE-3519:
-----------------------------------
Summary: `inheritPath` of `RelHint` represented by
`ImmutableBitSet` may be incomplete.
Key: CALCITE-3519
URL: https://issues.apache.org/jira/browse/CALCITE-3519
Project: Calcite
Issue Type: Bug
Components: core
Affects Versions: 1.21.0
Reporter: Shuo Cheng
Fix For: 1.22.0
Taking the following SQL with hint for example: (Copying from
`org.apache.calcite.test.SqlHintsConverterTest.testQueryHint `)
{code:java}
select /*+ properties(k1='v1', k2='v2'), index(ename), no_hash_join */
from emp e1
inner join dept d1 on e1.deptno = d1.deptno
inner join emp e2 on e1.ename = e2.job{code}
rel plan with hints should be following according to the hint design doc:
{code:java}
LogicalProject(EMPNO=[$0],...）([PROPERTIES inheritPath:[] options:{K1=v1,
K2=v2}],[INDEX inheritPath:[] options:[ENAME]],[NO_HASH_JOIN inheritPath:[]])
LogicalJoin(condition=[=($1, $20)], joinType=[inner]) ([NO_HASH_JOIN
inheritPath:[0]])
LogicalJoin(condition=[=($7, $9)], joinType=[inner]) (NO_HASH_JOIN
inheritPath:[0, 0]])
LogicalTableScan(table=[[CATALOG, SALES, EMP]]) ([PROPERTIES
inheritPath:[0, 0, 0] options:{K1=v1, K2=v2}], [INDEX inheritPath:[0, 0, 0]
options:[ENAME]])
LogicalTableScan(table=[[CATALOG, SALES, DEPT]]) ([PROPERTIES
inheritPath:[0, 0, 1] options:{K1=v1, K2=v2}], [INDEX inheritPath:[1, 0, 0]
options:[ENAME]])
LogicalProject(EMPNO=[$0], ENAME=[$1], JOB=[$2], MGR=[$3],...)
LogicalTableScan(table=[[CATALOG, SALES, EMP]]) ([PROPERTIES
inheritPath:[0, 1, 0] options:{K1=v1, K2=v2}], [INDEX inheritPath:[0, 1, 0]
options:[ENAME]]){code}
But the expected result of `SqlHintsConverterTest.testQueryHint` violates the
intention of Hint design doc.
