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

Example 1 with CoalesceOperator

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

the class DingoJobVisitor method visit.

@Override
public Collection<Output> visit(@Nonnull DingoCoalesce rel) {
    Collection<Output> inputs = dingo(rel.getInput()).accept(this);
    int size = inputs.size();
    if (size <= 1) {
        return inputs;
    }
    Output one = inputs.iterator().next();
    boolean isToSumUp = one.isToSumUp();
    Operator operator = isToSumUp ? new SumUpOperator(size) : new CoalesceOperator(size);
    operator.setId(idGenerator.get());
    Task task = one.getTask();
    task.putOperator(operator);
    int i = 0;
    for (Output input : inputs) {
        assert input.getTask().equals(task) : "Operator linked must be in the same task.";
        assert input.isToSumUp() == isToSumUp : "All inputs must have the same \"toSumUp\" hint.";
        input.setLink(operator.getInput(i));
        ++i;
    }
    return operator.getOutputs();
}
