What is a UUID v4?A UUID (Universally Unique Identifier) is a 128-bit number used to uniquely identify information in computer systems. UUID v4 is a specific version that generates random UUIDs, ensuring a near-zero chance of duplication. Here’s what makes UUID v4 special:

  • Randomness: UUID v4 is generated using random or pseudo-random numbers.
  • Uniqueness: The probability of generating the same UUID twice is extremely low.
  • Wide Adoption: UUIDs are supported by most programming languages and databases.

UUIDs are commonly used for:

  • Database records (e.g., primary keys).
  • Session IDs in web applications.
  • File names or resource identifiers.
  • Distributed systems and microservices.
