WebOpen Addressing. Open addressing is when. All the keys are kept inside the hash table, unlike separate chaining. The hash table contains the only key information. The methods … WebRight, naive double hashing is not cache friendly as well, because of the same hash keys are far away from each other, so each key access generates a "cache miss". The best strategy would be to use a more sophisticated hash table. Most of the library hash tables use the same exact technique: buckets of keys/values to amortize cache misses.
