Worst-case optimal join algorithms are attractive from a theoretical point of view, as they offer
asymptotically better runtime than binary joins on certain types of queries. In particular, they
avoid enumerating large intermediate results by processing multiple input relations in a
single multi-way join. However, existing implementations incur a sizable overhead in
practice, primarily since they rely on suitable ordered index structures on their input.
