Examples with HashAggregateNode org.apache.ignite.internal.sql.engine.exec.rel.HashAggregateNode used on opensource projects

Example 1 with HashAggregateNode

use of org.apache.ignite.internal.sql.engine.exec.rel.HashAggregateNode in project ignite-3 by apache.

the class LogicalRelImplementor method visit.

/**
 * {@inheritDoc}
 */
@Override
public Node<RowT> visit(IgniteReduceHashAggregate rel) {
    AggregateType type = AggregateType.REDUCE;
    RelDataType rowType = rel.getRowType();
    Supplier<List<AccumulatorWrapper<RowT>>> accFactory = expressionFactory.accumulatorsFactory(type, rel.getAggregateCalls(), null);
    RowFactory<RowT> rowFactory = ctx.rowHandler().factory(ctx.getTypeFactory(), rowType);
    HashAggregateNode<RowT> node = new HashAggregateNode<>(ctx, rowType, type, rel.getGroupSets(), accFactory, rowFactory);
    Node<RowT> input = visit(rel.getInput());
    node.register(input);
    return node;
}

Example 2 with HashAggregateNode

use of org.apache.ignite.internal.sql.engine.exec.rel.HashAggregateNode in project ignite-3 by apache.
