Examples with ExplainStatementPlan com.hazelcast.jet.sql.impl.SqlPlanImpl.ExplainStatementPlan used on opensource projects

Example 1 with ExplainStatementPlan

use of com.hazelcast.jet.sql.impl.SqlPlanImpl.ExplainStatementPlan in project hazelcast by hazelcast.

the class CalciteSqlOptimizer method toExplainStatementPlan.

private SqlPlan toExplainStatementPlan(PlanKey planKey, OptimizerContext context, QueryParseResult parseResult) {
    SqlNode node = parseResult.getNode();
    assert node instanceof SqlExplainStatement;
    QueryConvertResult convertResult = context.convert(((SqlExplainStatement) node).getExplicandum());
    PhysicalRel physicalRel = optimize(parseResult.getParameterMetadata(), convertResult.getRel(), context, false);
    return new ExplainStatementPlan(planKey, physicalRel, planExecutor);
}

Example 2 with ExplainStatementPlan

use of com.hazelcast.jet.sql.impl.SqlPlanImpl.ExplainStatementPlan in project hazelcast by hazelcast.

the class PlanExecutor method execute.

SqlResult execute(ExplainStatementPlan plan) {
    Stream<String> planRows;
    SqlRowMetadata metadata = new SqlRowMetadata(singletonList(new SqlColumnMetadata("rel", VARCHAR, false)));
    InternalSerializationService serializationService = Util.getSerializationService(hazelcastInstance);
    planRows = Arrays.stream(plan.getRel().explain().split(LE));
    return new SqlResultImpl(QueryId.create(hazelcastInstance.getLocalEndpoint().getUuid()), new StaticQueryResultProducerImpl(planRows.map(rel -> new JetSqlRow(serializationService, new Object[] { rel })).iterator()), metadata, false);
