About UUID
A UUID (Universally Unique Identifier) is a 128-bit value used to uniquely identify information in computer systems. The standard form is 32 hexadecimal digits separated by hyphens: xxxxxxxx-xxxx-Mxxx-Nxxx-xxxxxxxxxxxx
UUID v4 is generated using random numbers, making it suitable for most use cases where guaranteed global uniqueness is needed without a central coordinator.
UUID v1 is timestamp-based and includes the MAC address of the generating machine. This makes it sortable by creation time but may expose system information.
