About UUIDs
UUIDs (Universally Unique Identifiers) are 128-bit identifiers that are unique across both space and time, with minimal coordination between systems generating them.
UUID v4 (Random)
Generated using random numbers. This is the most common type of UUID and is suitable for most applications. The probability of a collision is extremely low.
UUID v1 (Time-based)
Generated based on the current timestamp and a unique node identifier. These are guaranteed to be unique if the node identifier is unique.
UUID v5 (Namespace-based)
Generated by hashing a namespace identifier and a name using SHA1.
