In PlannerTest, we can freely set the rule set of hep planner and volcano
planner by writing the following. So this PR does not need to be continued, I
will close it.
```
@Test void testPlanTransform() throws Exception {
// Create two dummy rules with identical rules.
RelOptRule rule1 = MyProjectFilterRule.config("MYRULE").toRule();
RelOptRule rule2 = MyFilterProjectRule.config("MYRULE").toRule();
RuleSet ruleSet1 =
RuleSets.ofList(rule1,
EnumerableRules.ENUMERABLE_TABLE_SCAN_RULE,
EnumerableRules.ENUMERABLE_FILTER_RULE,
EnumerableRules.ENUMERABLE_PROJECT_RULE);
RuleSet ruleSet2 = RuleSets.ofList(rule2);
Planner planner =
getPlanner(null,
// using hep program
Programs.hep(ruleSet1, true,
DefaultRelMetadataProvider.INSTANCE),
// using volcano program
Programs.of(ruleSet2));
SqlNode parse = planner.parse("select * from \"emps\"");
SqlNode validate = planner.validate(parse);
RelNode convert = planner.rel(validate).rel;
RelTraitSet traitSet = convert.getTraitSet()
.replace(EnumerableConvention.INSTANCE);
// This can do optimize in hep planner with ruleSet1
RelNode transform = planner.transform(0, traitSet, convert);
// This can do optimize in volcano planner with ruleSet2
RelNode transform2 = planner.transform(1, traitSet, transform);
assertThat(toString(transform2),
equalTo(
"EnumerableProject(empid=[$0], deptno=[$1], name=[$2],
salary=[$3], commission=[$4])\n"
+ " EnumerableTableScan(table=[[hr, emps]])\n"));
}
```
