Optimizing for First n-tuples
Traditional techniques optimize time to get all tuples.
- It is much better to optimize time to
get first n-tuples.
-
Little theory available on such optimization
- May be counter-intuitive from the point of view of traditional optimization
- Use of double-pipe-lined hash join in TUKWILA
- Cost-quality tradeoffs (not all answers are equal..)
