Manas Joglekar, Rohan Puttagunta, Christopher Ré
We study a class of aggregate-join queries with multiple aggregation operators evaluated over annotated relations. We show that straightforward extensions of standard multiway join…
It's all a matter of degree: Using degree information to optimize multiway joins
