why twitter call it SnowFlake

the name told its meaning.

There is a theorem states that there is not existed two identical snow flake, neither the sequence ID in the database.This is the first reason.

The second reason is the way they generate the sequence ID. The snow flake generated by the combination of various conditions: wind, temperature, moisture, atmosphere and so on. All these conditions are geographical and time factors, so are the sequence ID.Twitter generate the sequence ID based on server I and the generated ID.

This is the old trick for yet a new problems.

More on the k-sorted algorithm later.
