Example 1 with JoinCommuteRule

use of org.apache.calcite.rel.rules.JoinCommuteRule in project beam by apache.

the class ZetaSQLQueryPlanner method modifyRuleSetsForZetaSql.

private static Collection<RuleSet> modifyRuleSetsForZetaSql(Collection<RuleSet> ruleSets, Collection<RelOptRule> calc) {
    ImmutableList.Builder<RuleSet> ret = ImmutableList.builder();
    for (RuleSet ruleSet : ruleSets) {
        ImmutableList.Builder<RelOptRule> bd = ImmutableList.builder();
        for (RelOptRule rule : ruleSet) {
            // requires the JoinCommuteRule, which doesn't work without struct flattening.
            if (rule instanceof JoinCommuteRule) {
                continue;
            } else if (rule instanceof FilterCalcMergeRule || rule instanceof ProjectCalcMergeRule) {
                // planning result eventually.
                continue;
            } else if (rule instanceof BeamCalcRule) {
                bd.addAll(calc);

Example 2 with JoinCommuteRule

use of org.apache.calcite.rel.rules.JoinCommuteRule in project beam by apache.

the class ThreeTablesSchema method testSystemNotReorderingWithoutRules.

@Test

    TestTableProvider tableProvider = new TestTableProvider();
    createThreeTables(tableProvider);
    List<RelOptRule> ruleSet = BeamRuleSets.getRuleSets().stream().flatMap(rules -> StreamSupport.stream(rules.spliterator(), false)).filter(rule -> !(rule instanceof BeamJoinPushThroughJoinRule)).filter(rule -> !(rule instanceof BeamJoinAssociateRule)).filter(rule -> !(rule instanceof JoinCommuteRule)).collect(Collectors.toList());
    BeamSqlEnv env = BeamSqlEnv.builder(tableProvider).setPipelineOptions(PipelineOptionsFactory.create()).setRuleSets(ImmutableList.of(RuleSets.ofList(ruleSet))).build();
    // This is Join(Join(medium, large), small) which should be converted to a join that large table
    // is on the top.
    BeamRelNode parsedQuery = env.parseQuery("select * from medium_table " + " JOIN large_table on large_table.medium_key = medium_table.large_key " + " JOIN small_table on medium_table.small_key = small_table.medium_key ");
