A young computer scientist and two colleagues show that searches within data structures called hash tables can be much faster than previously deemed possible.
I’ve only used java but java hash tables are stupid fast in my experience, like everything else in my crap programs was 1000 times slower than the hash table access or storage.
Just reading the title, it’s talking about searching hash tables, which wasn’t something I was specifically doing.
I don’t think the speed of hash tables is a problem in most applications except benchmarks.
Hash tables are often used behind the scenes. dicts and sets in python both utilize hash tables internally, for example.

If you use a hash table, you search every time you retrieve an object.
If you didn’t retrieve, why would you be storing the data in the first place?
I know that, but phrased that way it sort of sounds like they’re iterating over the entire thing.
