UUIDs in MySQL are really not random

This is quite funny. Anyone who has used UUIDs for a while realizes that they tend to cluster. Relying on them for randomness is effective as the old xkcd joke: https://xkcd.com/221/.

They are certainly useful for creating unique id's, but for randomness? No.

Anyone who has used UUIDs should be aware that there are different UUIDs. In fact, UUID3,4 and 5 are all generally random. UUID4 depending on the quality of your RNG and 3 and 5 depending on the quality of the input data.
