常见问题
How many UUIDs before collision is likely?
For a 50% collision chance with UUID v4 (122 random bits), you need ~2.7 x 10^18 UUIDs. For 1 billion UUIDs, collision probability is ~0.00000000003%.
Why is log2 important in system design?
log2(n) tells you the minimum bits needed to represent n items. It also gives the depth of a balanced binary tree with n leaves, and the number of binary search steps.
