Examples with PlanOptimizers com.facebook.presto.sql.planner.PlanOptimizers used on opensource projects

Example 1 with PlanOptimizers

use of com.facebook.presto.sql.planner.PlanOptimizers in project presto by prestodb.

the class LocalQueryRunner method createPlan.

public Plan createPlan(Session session, @Language("SQL") String sql, LogicalPlanner.Stage stage) {
    Statement statement = unwrapExecuteStatement(sqlParser.createStatement(sql), sqlParser, session);
    assertFormattedSql(sqlParser, statement);
    FeaturesConfig featuresConfig = new FeaturesConfig().setDistributedIndexJoinsEnabled(false).setOptimizeHashGeneration(true);
    PlanOptimizers planOptimizers = new PlanOptimizers(metadata, sqlParser, featuresConfig, true, new MBeanExporter(new TestingMBeanServer()));
    return createPlan(session, sql, planOptimizers.get(), stage);
}

Example 2 with PlanOptimizers

use of com.facebook.presto.sql.planner.PlanOptimizers in project presto by prestodb.

the class AbstractTestQueryFramework method getQueryExplainer.

private QueryExplainer getQueryExplainer() {
    Metadata metadata = queryRunner.getMetadata();
    FeaturesConfig featuresConfig = new FeaturesConfig().setOptimizeHashGeneration(true);
    boolean forceSingleNode = queryRunner.getNodeCount() == 1;
    TaskCountEstimator taskCountEstimator = new TaskCountEstimator(queryRunner::getNodeCount);
