Re: Is this comparison valid?
Posts: n/a
The order of the strings is non-deterministic BETWEEN RUNS, but not
any other way. After a shuffle, the order is randomized. That can
be done as many times as you want / need in a single run of the
program. And two sets of keys with some overlap will be reliably
randomly ordered after a shuffle, but not after hashing.

In some limited cases, hashing may be "random" enough, but do remember
that is is based on a formula applied to the key string, whereas a
shuffle is a rearrangement that ignores the data altogether.


Thank you for the explanation.
