示例1: register
import org.apache.calcite.rel.rules.JoinUnionTransposeRule; //导入依赖的package包/类
@Override
public void register(RelOptPlanner planner) {
// force clear the query context before traversal relational operators
OLAPContext.clearThreadLocalContexts();
// register OLAP rules
addRules(planner, kylinConfig.getCalciteAddRule());
planner.addRule(OLAPToEnumerableConverterRule.INSTANCE);
planner.addRule(OLAPFilterRule.INSTANCE);
planner.addRule(OLAPProjectRule.INSTANCE);
planner.addRule(OLAPAggregateRule.INSTANCE);
planner.addRule(OLAPJoinRule.INSTANCE);
planner.addRule(OLAPLimitRule.INSTANCE);
planner.addRule(OLAPSortRule.INSTANCE);
planner.addRule(OLAPUnionRule.INSTANCE);
planner.addRule(OLAPWindowRule.INSTANCE);
// Support translate the grouping aggregate into union of simple aggregates
planner.addRule(AggregateMultipleExpandRule.INSTANCE);
planner.addRule(AggregateProjectReduceRule.INSTANCE);
// CalcitePrepareImpl.CONSTANT_REDUCTION_RULES
planner.addRule(ReduceExpressionsRule.PROJECT_INSTANCE);
planner.addRule(ReduceExpressionsRule.FILTER_INSTANCE);
planner.addRule(ReduceExpressionsRule.CALC_INSTANCE);
planner.addRule(ReduceExpressionsRule.JOIN_INSTANCE);
// the ValuesReduceRule breaks query test somehow...
// planner.addRule(ValuesReduceRule.FILTER_INSTANCE);
// planner.addRule(ValuesReduceRule.PROJECT_FILTER_INSTANCE);
// planner.addRule(ValuesReduceRule.PROJECT_INSTANCE);
removeRules(planner, kylinConfig.getCalciteRemoveRule());
// since join is the entry point, we can't push filter past join
planner.removeRule(FilterJoinRule.FILTER_ON_JOIN);
planner.removeRule(FilterJoinRule.JOIN);
// since we don't have statistic of table, the optimization of join is too cost
planner.removeRule(JoinCommuteRule.INSTANCE);
planner.removeRule(JoinPushThroughJoinRule.LEFT);
planner.removeRule(JoinPushThroughJoinRule.RIGHT);
// keep tree structure like filter -> aggregation -> project -> join/table scan, implementOLAP() rely on this tree pattern
planner.removeRule(AggregateJoinTransposeRule.INSTANCE);
planner.removeRule(AggregateProjectMergeRule.INSTANCE);
planner.removeRule(FilterProjectTransposeRule.INSTANCE);
planner.removeRule(SortJoinTransposeRule.INSTANCE);
planner.removeRule(JoinPushExpressionsRule.INSTANCE);
planner.removeRule(SortUnionTransposeRule.INSTANCE);
planner.removeRule(JoinUnionTransposeRule.LEFT_UNION);

planner.removeRule(AggregateUnionTransposeRule.INSTANCE);
planner.removeRule(DateRangeRules.FILTER_INSTANCE);
planner.removeRule(SemiJoinRule.JOIN);
planner.removeRule(SemiJoinRule.PROJECT);
// distinct count will be split into a separated query that is joined with the left query
planner.removeRule(AggregateExpandDistinctAggregatesRule.INSTANCE);
