- The first question is actually a classic question about the database execution model, Nebula is currently using materialization model, so the operator "executes after get all results." We're also working on vectorization model internally, which should be released sometime next year. You can think of this as what you say "start the subquery immediately after obtaining partial results in pipe sentence".
- The second question, "sub sentence may be concurrent ". I think that's what Nebula is doing now, and you can use explain statement to view your execution plan.
