Examples with SortOperator - io.dingodb.exec.operator.SortOperator

Example 1 with SortOperator

use of io.dingodb.exec.operator.SortOperator in project dingo by dingodb.

the class DingoJobVisitor method visit.

@Override
public Collection<Output> visit(@Nonnull DingoSort rel) {
    Collection<Output> inputs = dingo(rel.getInput()).accept(this);
    List<Output> outputs = new LinkedList<>();
    for (Output input : inputs) {
        Operator operator = new SortOperator(rel.getCollation().getFieldCollations().stream().map(c -> new SortCollation(c.getFieldIndex(), c.direction, c.nullDirection)).collect(Collectors.toList()), rel.fetch == null ? -1 : RexLiteral.intValue(rel.fetch), rel.offset == null ? 0 : RexLiteral.intValue(rel.offset));
        Task task = input.getTask();
        operator.setId(idGenerator.get());
        task.putOperator(operator);
        input.setLink(operator.getInput(0));
        operator.getSoleOutput().copyHint(input);
        outputs.addAll(operator.getOutputs());
    }
    return outputs;
}
