示例1: register

import org.apache.kylin.query.optrule.OLAPSortRule; //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
    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);

    // since join is the entry point, we can't push filter past join
    planner.removeRule(PushFilterPastJoinRule.FILTER_ON_JOIN);
    planner.removeRule(PushFilterPastJoinRule.JOIN);

    // TODO : since we don't have statistic of table, the optimization of join is too cost
    planner.removeRule(SwapJoinRule.INSTANCE);
    planner.removeRule(PushJoinThroughJoinRule.LEFT);
    planner.removeRule(PushJoinThroughJoinRule.RIGHT);

    // for columns in having clause will enable table scan filter rule
    // cause kylin does not depend on MPP
    planner.removeRule(PushFilterPastProjectRule.INSTANCE);
    // distinct count will be split into a separated query that is joined with the left query
    planner.removeRule(RemoveDistinctAggregateRule.INSTANCE);
    
    // see Dec 26th email @ http://mail-archives.apache.org/mod_mbox/calcite-dev/201412.mbox/browser
    planner.removeRule(ExpandConversionRule.INSTANCE);
