Summary

Worst-case optimal join algorithms offer better runtime than binary joins on certain queries, but existing implementations have sizable overhead due to reliance on ordered index structures. A new approach is presented, using a hash-based worst-case optimal join algorithm and a hybrid query optimizer, which outperforms existing systems on complex analytical workloads without sacrificing performance on traditional benchmarks.
