I've always admired the wizardry of Cliff Click's concurrent hash: http://www.azulsystems.com/blog/cliff/2007-03-26-non-blocking-hashtable http://www.azulsystems.com/blog/cliff/2007-03-26-non-blockin... https://youtu.be/HJ-719EGIts https://youtu.be/HJ-719EGIts I'm not sure what to make of an "atomic" hash. I don't think OP does as well: "Doesn't this kind of defeat the point of concurrent algorithms? Well, in a sense, it does make it non-atomic, but it isn't really a spin-lock or anything like that, even though it can seem like that:" Concurrent hash seems to be more correct and clear.
