Copy individual IDs or the entire list. Essential for database primary keys, API resource identifiers, and session tokens.

अक्सर पूछे जाने वाले सवाल
Will UUIDs ever collide?+
UUID v4 generates 122 bits of randomness, yielding 5.3 × 10^36 possible values. You would need to generate 2.71 × 10^18 UUIDs to have a 50% chance of a single collision. For practical purposes, collisions are impossible.
When should I use UUID vs auto-increment?+
Use UUIDs when you need: globally unique IDs across distributed systems, IDs that don't reveal record count or creation order, or IDs generated client-side before database insertion. Use auto-increment for simpler, more compact, sortable IDs in single-database systems.
