Practical implications of bubble-up cuckoo hashing

Identify whether the techniques underlying bubble-up cuckoo hashing yield useful lessons for the design of real-world hash tables.

Background

The paper leaves unresolved whether the structural ideas used to obtain near-optimal space efficiency and efficient insertion and positive-query operations can inform practical hash-table implementations or designs.
