why isn't bucket sort (on the whole dataset) applicable in your situation?

  1. How do you divide a (minimum) input range of 2^64, with a typical 100GB dataset representing just 0.00000007275957614183% of that range; into buckets?
  2. Because it is O(N2) worst case.

    But no indication of what provokes that worst case.

  3. Because it requires O(N+K) space worst case.

    (With no indication that I can see for what K is.)

  4. Because I haven't seen anything about a bucket sort that makes it a candidate for the problem?

    (A radix sort has possibilities; but I haven't gotten to pursuing them.)

Examine what is said, not who speaks -- Silence betokens consent -- Love the truth but pardon error.

In the absence of evidence, opinion is indistinguishable from prejudice. Agile (and TDD) debunked
